Engineering practice fields

Aerospace engineering is the design, development and production of aircraft (aeronautical engineering), spacecraft (astronautical engineering) and related systems. Aerospace engineers may specialise in aerodynamics, avionics, structures, control systems or propulsion systems. It may involve planning maintenance programmes, designing repairs and modifications and exercising strict and quality controls to ensure airworthy operations.

Asset Management involves evaluating multiple complex factors to predict, assess and manage asset condition, performance, maintenance and renewals, with a view to balancing cost, performance and risk. It encompasses cross-disciplinary expertise and deals with complex engineering issues. Asset Management Engineering differs from general Asset Management, as it requires a deeper technical understanding of complexity and risk, engineering materials, structural performance and systems behaviour over time. It also relies on interdisciplinary collaboration and long-term financial planing, particularly within climate adaptation and sustainability frameworks, to support robust lifecycle decisions. The field is guided by internationally and locally recognised standards and practice guidance such as the Āpōpō Guide, the New Zealand Infrastructure Asset Valuation and Depreciation Guidelines, the Global Forum on Maintenance and Asset Management's (GFMAM) Asset Management Landscape V3, the ISO 55000 suite, the International Infrastructure Management (IIMM), and the International Infrastructure Financial Management Manual (IIFMM), which are widely adopted as best-practice references.

Bioengineering draws heavily on the Chemical engineering discipline and involves the engineered development of raw materials to produce higher value products, using biological systems (biological catalysts). The description also encompasses the general application of engineering to biological systems to develop new products or solve problems in existing production processes. As examples, bioengineers are found in medical research, genetic science, fermentation industries and industries treating biological wastes.

Building Services engineering is the application of mechanical, electrical and electronics and fire protection engineering principles, to enhance all aspects of the built environment from air conditioning and mechanical ventilation, electrical light and power, active fire protection services (e.g. sprinklers and alarms), water and waste services, information and communication technology, security and access control, and vertical transportation. Building Services engineering involves coordination with and an understanding of related building disciplines including structure, architecture, fire engineering (passive life safety features), and civil water and waste infrastructure and coordination and interfacing between the various building services sub-disciplines.  The Building Services field is guided by international and local standards and the New Zealand Building Code where it is applicable to the various building services sub disciplines.Find out more

Chemical engineering is concerned with the ways in which raw materials are changed into useful and commercial end products such as food, petrol, plastics, paints, paper, ceramics, minerals and metals. Often these processes are carried out at large scale plants. Research of raw materials and their properties, design and development and equipment and the evaluation of operating processes are all part of chemical engineering.

Civil engineering is a broad field of engineering concerned with the design, construction, operation and maintenance of structures (buildings, bridges, dams, ports) and infrastructure assets (road, rail, water, sewerage). The Civil engineering discipline underpins several engineering fields such as Structural, Mining, Geotechnical and Transportation engineering, in which civil engineers often specialise. General civil engineers are likely to be competent to undertake work that relates to one or more of these areas.

Construction Engineering is the professional engineering discipline concerned with the engineering and execution of physical construction works, including the tendering, constructability, construction methodology, planning, construction management, and commissioning/decommissioning of built assets across their construction lifecycle. Practitioners apply professional engineering judgement in live construction environments or in roles directly accountable for construction-phase engineering decisions. Their decisions materially influence safety, constructability, construction-phase technical risk, construction performance, regulatory compliance, cost, programme, and delivery outcomes of construction projects. Construction Engineering can apply to multiple engineering disciplines (e.g. civil, structural, geotechnical, mechanical, electrical, fire, water etc.) where professional engineering judgement is exercised specifically in relation to how assets are constructed, rather than solely how they are permanently designed. It may be a standalone field of practice or applied alongside another technical practice field.Find out more

Electrical Engineering is the field of engineering which deals with the practical application of electricity. It deals with the aspects of planning, design, operation and maintenance of electricity generation and distribution, and the use of electricity within major buildings, industrial processing, infrastructure, facilities and transport systems. It includes the associated networks, and the equipment involved such as switchboards, cabling, overhead lines / catenaries, earthing, control and instrumentation systems. Electrical engineering spans the generation, transmission, distribution and use of electrical energy, together with the electronic, control, instrumentation and communication systems used to monitor, protect and operate electrical plants and processes. It therefore includes specialisations such as power systems, power electronics, electrical machines, control and instrumentation, electronics, and embedded systems. Some specialisations overlap with the related field of information engineering, particularly those concerned principally with transmitting, processing or storing information rather than energy, such as radio communications and telecommunications. The boundary between the two is not rigid, and many engineers work across both. Applicants should seek registration in the field that best reflects most of their professional competence; assessment under one field implies no lesser standing in the other. Find out more

The Academic practice field is defined for engineering academic staff members from tertiary education including engineering researchers.In tertiary education, academic staff members may be involved in engineering activities in various roles, from building engineering prototypes, to contributing to knowledge in engineering. Engineering academic staff members may not be directly involved in the engineering design process but undertaking cutting edge engineering research to lead and enhance engineering activities. Examples of work samples of engineering academic staff members may be their authored quality assurance publications in engineering disciplines, and/or their authored quality assurance engineering reports at NZQA level 7, 8, 9 or 10 (graduate or postgraduate level). Academic staff members who are teaching an engineering programme without quality assurance publications in engineering disciplines or quality assurance engineering reports, may not qualify for academic practice field.Find out more

Engineering Management is a field of practice where engineers from any technical engineering background exercise engineering judgement and use their knowledge and skills to manage people, projects, and resources to achieve required outcomes in related processes or business activities that contain multi-disciplinary frameworks.  An Engineering Management practitioner may work in areas on activities requiring complex decision making on frameworks that may not include technical activities. Alternatively, engineering managers may use their technical skills as well as general or business management skills and may or may not be directly involved in the engineering process. Engineering management differs from project management in that it requires applying engineering judgment and technical expertise to manage complex, interconnected organisational systems with uncertain variables and conflicting goals, whereas project management focuses more narrowly on planning and delivering specific projects within defined scope, time, and resource constraints.  In order to become an Engineering Management practitioner, it is expected that an applicant will have previously demonstrated their competence as a professional engineer (i.e. through a CPEng assessment or similar) and have undertaken some form of advanced business management training before applying for this practice field. Key responsibilities include, but are not limited to, governance, resource allocation, budgeting, and team leadership. Practitioners must possess a strong foundation in both technical and general management skills to guide diverse teams and ensure organizational cohesion. The following aspects differentiate Engineering Management from other (similar) practice fields and the management of engineering work competency grouping for other practice fields:The number of involved variables be they technical or business.Connectivity of the management process – how the elements are connected and work together, impacting each other when the engineer makes changes.The role of time and developments within an organisation. How will changes impact other parts of the organisation or operation with time, and what is required to deal with those impacts?The lack of transparency (in part or full) about the involved variables in the organisation or operation and their current values i.e. there will be unknown unknowns.Conflicting goals – there are likely to be goal conflicts, where altering one part of the system negatively impacts another.Find out more

Environmental engineering draws on the Civil and Chemical engineering disciplines to provide healthy water, air and land to enhance human habitation. Environmental engineers devise, implement and manage solutions to protect and restore the environment, within an overall framework of sustainable development. The role of the environmental engineer embraces all of the air, water and soil environments, and the interactions between them.

Fire engineering draws on knowledge from the range of engineering disciplines to minimise the risk from fire to health and safety and damage to property through careful design and construction. It requires an understanding of the behaviours of fires and smoke, the behaviour of people exposed to fires and the performance of burning materials and structures, as well as the impact of fire protection systems including detection, alarm and extinguishing systems.

Geotechnical engineering applies the principles of soil and rock mechanics to the design, construction, and performance monitoring of ground and ground-interacting structures.  It encompasses investigation, interpretation, analysis, design, risk management, and performance verification of the ground and ground-related systems across all project phases, from initial option evaluation through to construction and post-construction performance. Geotechnical engineering involves managing the uncertainty in ground conditions through the development and iterative refinement of ground models, supported by investigation, monitoring, and engineering judgement. It delivers solutions aligned with New Zealand practice, the Building Code, and relevant New Zealand Geotechnical Society (NZGS) and Ministry of Business, Innovation, and Employment (MBIE) guidance. Geotechnical engineering integrates local knowledge, environmental stewardship, and ethical professional standards throughout the engineering process, while collaborating closely with other disciplines to ensure effective performance.  For further detail on the knowledge, skills, and competencies expected of a CPEng Geotechnical Engineer, applicants and assessors should refer to the Chartered Professional Engineer (Geotechnical) Body of Knowledge and Skills. Find out more

Industrial engineers typically work in, for, or in close connection with industrial facilities and operations.Find out more

Information engineering is based on the Electrical engineering discipline but also draws heavily from Computer Science. Three areas of further specialisation can be identified: Software engineering – the development and operation of software-intensive systems that capture, store and process data. Telecommunications engineering – the development and operation of systems that encode, transmit and decode data via cable systems (including fibre optics) and wireless systems (radiocommunications). Electronics engineering – the design, development and testing of electronic circuits and networks that use the electrical and electromagnetic properties of electronic components integrated circuits and microprocessors to sense, measure and control processes and systems.

Mechanical engineering is the branch of professional engineering concerned with research and analysis, design and development, manufacture, testing, commissioning, operation, maintenance and decommissioning of mechanical systems, equipment, structures and machinery. It applies principles of mechanics of machines, structural mechanics, materials science, thermodynamics, fluid dynamics and control systems to develop safe, reliable and efficient solutions to complex engineering problems. Mechanical engineers exercise professional judgement to manage risk, ensure compliance with relevant legislation and standards, and optimise performance across the full asset lifecycle. Practice spans multiple industries, including energy, manufacturing, transport, water, process and building services systems.Find out more

Integrates specialist knowledge in mechanics, electronics and computer systems to design and develop integrated automated systems, such as chassis-stabilising systems, anti-lock brakes, engine control units, disk drives, cameras, service and surgical robots and medical devices. Often these systems are largely mechanical in nature but could not function without their essential electronic and computer control system components.

Mining engineering involves extracting and processing minerals from the earth. This may involve investigations, design, construction and operation of mining, extraction and processing facilities.

Petroleum engineering is a field of engineering relating to oil and gas exploration and production. Petroleum engineers typically combine knowledge of geology and earth sciences with specialised Chemical engineering skills, but may also draw on Mechanical engineering expertise to design extraction and production methods and equipment. Petroleum engineering activities are divided into two broad categories: Upstream – locating oil and gas beneath the earth's surface and then developing methods to bring them out of the ground. Downstream – the design and development of plant and infrastructure for the refinement and distribution of the mixture of oil, gas and water components that are extracted.

Software engineers apply the process of analysing user needs and designing, constructing, and testing end user applications that will satisfy these needs through the use of software programming languages. A fundamental aspect is the application of engineering principals to software development. In contrast to simple programming, software engineering is used for longer and more complex software systems, which are used as critical systems for business and organisations.

Structural Engineering is a specialised field within the broader Civil engineering discipline that is concerned with the design, construction monitoring and assessment of structures. Structures might include buildings, bridges, wharves, towers, retaining walls, temporary works, in-ground structures and reservoirs. To do this, Structural Engineers perform activities such as: Defining and scoping the client brief during project establishment. Design and analysis of structures to meet the client brief, including options assessment. Development of structural specifications and reports; and supervision or development of structural drawings and/or BIM models. Structural performance assessment of existing structures, including definition of investigations. Structural inspections, development of maintenance and rehabilitation plans. Design of repairs and strengthening for existing structures. Construction monitoring.Find out more

Systems Engineering is a multidisciplinary, interdisciplinary engineering practice that integrates technical, human, and organisational elements to enable the successful realisation, operation, and retirement of engineered systems. A “system” in this context is an organized combination of interacting, interdependent elements - such as hardware, software, people, processes, and facilities - designed to work together to achieve a specific unified purpose or goal that the parts cannot achieve alone.Systems Engineering applies engineering principles, scientific and mathematical methods, and systems concepts to define, design, and manage complex systems across their lifecycles. Systems Engineers enable successful interfacing between disciplines by maintaining through-life visibility of stakeholder needs, ensuring integration, managing risk, and enabling systems to meet stakeholder and performance objectives.Key differentiators for Systems Engineering are that they consider the complete context of a problem, coordinate multidisciplinary teams to better understand and manage systems and their complexity, and they consider a system’s whole lifecycle and unique risk profile. To do this, Systems Engineers perform activities such as:Defining and scoping customer or stakeholder needs and required functionality early in the development cycle.Establishing appropriate system lifecycle models, processes, and governance structures, that take the levels of complexity, uncertainty, and change into consideration.Applying architectural and design skills to generate and evaluate alternative solution concepts and architectures.Developing agreed system specifications.Planning and performing structured validation, verification and integration of the sub-systems while continuously considering the complete system problem, and context of the system including interfacing systems and stakeholders. Find out more

Transportation engineering is a subset of civil engineering relating to the movement of goods and people on land, water, and in the air. All transport modes are included (e.g. driving, cycling, walking, micro-mobility, wheeled pedestrians, rail, aviation, and maritime), along with the infrastructure and services supporting those modes. The discipline seeks to provide safe, efficient, accessible, equitable, and environmentally sustainable movement of people and goods, supporting economic activity, health and community wellbeing.  In transportation engineering, the term ‘traffic’ relates to all modes of movement, not just motorised land-based vehicles, and ‘road’ in ‘road safety’ relates to all types of movement corridors (including carriageways, cycle facilities, pedestrian spaces, and urban environments).  Transportation engineering encompasses the planning, modelling, investigation, design, economic analysis, construction, operation, maintenance, and management of integrated, multi-modal transport systems. It uses data, modelling, and engineering judgement, while considering human behaviour, accessibility, and user experience.  Transportation Engineering recognises network performance and the relationships between land use, urban form, transport needs (and wants), along with the interactions between modes. Importantly, it considers human behaviour, accessibility and user experience in the design and operation of transport systems. Beyond traditional design, it includes policy development and regulatory frameworks, and incorporates emerging technologies, resilience to disruption, and adaptation to future transport needs. Find out more

Water Engineering is the professional engineering practice focused on the delivery and stewardship of water services across the full water cycle in New Zealand from source to receiving environment. It encompasses source water protection and catchment management, safe drinking water treatment and supply, wastewater collection, treatment and discharge, stormwater management, treatment residuals, and on-site or decentralised solutions where appropriate, with water infrastructure understood as interconnected systems where networks, treatment processes, natural environments, operational and digital systems interact dynamically.  Water Engineering is inherently interdisciplinary. Practice routinely blends civil and hydrological/hydraulic engineering, environmental engineering and science, chemical and process engineering, mechanical engineering, electrical, instrumentation and control engineering, asset management and systems thinking, and land use planning. Water engineers will typically work across several of these disciplines and integrate the work of others, reflecting the complexity and breadth of water systems.  Water engineers apply engineering principles and professional judgement to protect public health, the environment and community wellbeing while meeting regulatory requirements and supporting safe, reliable and sustainable infrastructure outcomes. Practice balances public health, environmental protection, flood and service risks, affordability, operability, maintainability, resilience and regulatory compliance, across day-to-day operations and whole-of-life asset decisions.  It spans the full lifecycle of water assets and systems, ensuring sustainability, resilience and climate change adaptation to manage uncertainty, growth and ageing infrastructure. Find out more
