How did you get into chemical engineering?

“I enjoyed chemistry, physics and calculus at high school and found that chemical engineering combined these subjects nicely. Engineering seemed like a good choice, with lots of different career pathways."

What are the main skills you need to be a good chemical engineer? 

“Problem solving, critical thinking and communication are essential skills in my role. I’m currently based at an industrial site, where problem solving and critical thinking are required every day to tackle new and existing issues.

“Being able to communicate clearly with site staff is also essential for effective project delivery, as well as for general consulting.”

What are some of the things you like about your job?

“I like the variety of work. I also enjoy seeing the real-world results of projects I have been a part of, and making a difference to a site's carbon emissions and energy consumption.”

Are there good job prospects with a career in chemical engineering?

“There is plenty of demand for chemical engineers so there are good career prospects. It's also a great career path to take with many different opportunities, where you can make a real, positive difference to the environment.

“There are also many prospects available such as project management opportunities or gaining more technical responsibility as your career progresses.”

To become a chemical engineer you need to have a four-year Bachelor of Engineering or Bachelor of Engineering Honours degree specialising in any of the following:

  • biochemical
  • bioprocessing
  • biotechnology
  • chemical and materials
  • chemical and process
  • chemical technology
  • materials and process.

Employers in the food manufacturing industry also accept a three-year Bachelor's degree in any of the following:

  • food process engineering
  • food science
  • food technology.

To work in research and development a higher degree, such as a Master of Engineering or relevant PhD, is required.

Secondary education

A tertiary entrance qualification is required to enter further training. Useful subjects include chemistry, maths, physics, and construction, mechanical and processing technologies.

Personal requirements

Chemical engineers need to be:

  • careful and safety-conscious
  • able to work well in a team and unsupervised
  • analytical and accurate, with an eye for detail
  • patient and methodical

What are the chances of getting a job?

Chemical engineers in demand

The number of chemical engineers is increasing but there are still not enough to meet demand. Demand is highest for experienced engineers, but there are still good opportunities for graduates.

Chemical engineer and the related job industrial engineer (process) appear on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled chemical engineers from overseas to work in New Zealand.

According to the Census, 471 chemical engineers worked in New Zealand in 2018.

Opportunities for chemical engineers in water infrastructure and chemical products

Job opportunities for chemical engineers are growing in the water industry as the clean water and waste water infrastructure throughout the country gets upgraded. There is also reasonable demand for engineers to oversee products of chemical engineering such as infant formula and fertilisers. 

Work across a range of industries

Chemical engineers usually work for organisations that make products or process materials, across a range of industries, such as:
  • agriculture, forestry and fisheries
  • construction and infrastructure
  • electricity, gas, water and waste services
  • energy and mining
  • food, beverage and dairy processing
  • heavy industry such as petroleum production, steel smelters and refineries
  • plastics, pharmaceutical and chemical production
  • professional, scientific and technical consulting
  • wood, pulp and paper processing.

Some chemical engineers work for city or district councils, or at universities or research institutes.
