What you will do

Microbiologists may do some or all of the following:

  • analyse and/or perform tests and experiments on micro-organisms
  • identify and characterise micro-organisms, including those that cause disease
  • develop and use micro-organisms for the production of fuels and chemicals
  • develop micro-organisms and the products of their growth for use in vaccines and medicines
  • grow micro-organisms to use in food such as yoghurt and cheese
  • identify micro-organisms that may pollute food, water and the environment
  • find ways for micro-organisms to help humans
  • prepare reports and papers, and present results
  • provide technical guidance to assistants.

Skills and knowledge

Microbiologists need to have:

  • knowledge of molecular biology and genetics, biochemistry and chemistry
  • practical skills for performing experiments and operating scientific equipment
  • knowledge of laboratory hazards and proper safety procedures
  • skill in analysing and interpreting research results and other information
  • problem-solving skills
  • presentation skills
  • writing skills, for reports or grant proposals
  • maths and computer skills.

Working conditions


  • typically work regular business hours, but for some projects may need to work evenings and weekends
  • work in laboratories and offices, but also work in the field collecting samples or performing field trials
  • may travel locally and overseas to attend workshops and conferences.

What's the job really like?

Kristin Dyet

Dr Kristin Dyet


A born do-gooder

As a postdoctoral scientist at ESR (Institute for Environmental and Science Research) in Porirua, Kristin Dyet loves that she is contributing towards improving public health through her work. "One thing I'm working on is developing methods to rapidly detect outbreaks of food poisoning. By detecting an outbreak early and determining its source, we can reduce the number of people who get sick."

Multitasking is key

On a typical day, Kristin carries out a number of diverse activities including setting up experiments, analysing data and writing reports. "I try to split the day to have some lab work and some computer work.

"You need to have multiple experiments running at the same time. It's not the type of job where you can focus on one experiment at a time, as experiments can run for weeks or months and don't require your attention all the time."

Sharing your findings is important

Telling people about the results of these experiments is becoming a bigger part of Kristin's job. "I think communication is an important aspect of a science-related career. What's the point of finding out something really important if you can't communicate to the world what you have found?"

Entry requirements

To become a microbiologist you need to have a Bachelor of Science, majoring in microbiology, biotechnology, biochemistry or molecular biology. 

A postgraduate qualification, such as a Master's degree or Doctorate, is usually required for those wanting to enter research-based positions.

Secondary education

A tertiary entrance qualification is required to enter further training. Useful subjects include biology, maths, chemistry and physics. 

Personal requirements

Microbiologists need to be:

  • patient, persistent and inquiring
  • analytical, accurate and careful
  • motivated
  • innovative
  • able to communicate complex ideas simply.

Useful experience

Useful experience for microbiologists includes laboratory work, or medical laboratory experience if working in a medical setting.

What are the chances of getting a job?

Limited opportunities for microbiologists doing fundamental research

Opportunities are limited for microbiologists doing basic or fundamental research, rather than research that is applied to practical areas. This is mainly because there is less funding for fundamental research. 

Government funding good for microbiologists doing applied research

Most microbiology funding is going to applied research. Through Budget 2016, the Government is investing $410.5 million over four years in science and innovation. By 2020, the annual investment in science and innovation will be 1.6 billion per year, which is one of the largest single investments in science and innovation in New Zealand history.

This will create opportunities for microbiologists involved in developing technologies and products such as new vaccines, foods and more recently, biofuels, which has become one of the larger opportunities for microbiologists in New Zealand. 

Types of employers varied

Microbiologists may work for:

  • Crown research institutes (CRIs)
  • universities
  • medical and veterinary laboratories
  • hospitals
  • biotechnology companies
  • agricultural product manufacturing companies
  • food manufacturing companies
  • private research institutes
  • breweries.

Progression and specialisations

Microbiologists first work as technicians or assistants during university or after graduating. As they gain lab and computer skills, they may progress to senior positions, or they may undertake postgraduate study to specialise in a particular research area.

Microbiologists who have earned a PhD typically have more control over their research projects. Because research funding is limited, they may work on a variety of fixed-term projects for different employers, but within their study area. After developing their research and communication skills, they may become project leaders.

Project leaders spend less time in the lab, and more time seeking funding for projects, and managing people, processes and resources.

Some microbiologists may also move into medical sales, policy work, teaching, journalism, law or business.
