How would you describe your job to a child?

"I help the doctor figure out what’s wrong with sick people. I work with poos, wees, blood, body parts. It sounds disgusting, but I find it fascinating.

What stands out from your first week at work?

"In histology – that's where they cut up the body tissue – you get the moles that get cut off, colons, an eyeball, once, a whole breast. I was just staring at the pottles."

What's the most important part of your job?

"We have a lot of responsibility. Say our tests showed a patient had a very low haemoglobin [oxygen-carrying protein in the blood] level. That means they could have loss of organ function, so before their whole body breaks down, we contact their doctor, so they can get hold of the patient and get them to hospital."

Entry requirements

To become a medical laboratory scientist you need to:

  • have a Bachelor of Medical Laboratory Science or a Graduate Diploma in Science
  • work for at least six months under supervision
  • be registered with the Medical Sciences Council of New Zealand
  • hold a current Annual Practising Certificate.

Graduate Diploma in Science an entry for technicians

Medical laboratory technicians can do a Graduate Diploma in Science or a Postgraduate Diploma in Medical Laboratory Science to become a medical laboratory scientist if they:

  • are a registered medical laboratory technician
  • have worked for at least a year in a New Zealand Medical Diagnostic Laboratory
  • have a Bachelor of Science or Bachelor of Biomedical Science.

Secondary education

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

Personal requirements

Medical laboratory scientists need to be:

  • methodical and accurate
  • careful and safety-conscious
  • enquiring and adaptable
  • good at problem solving
  • responsible and reliable
  • good at communicating.

Useful experience

Useful experience for medical laboratory scientists includes:

  • work in a medical laboratory

What are the chances of getting a job?

Chances of finding work as a medical laboratory scientist are good due to:

  • an ageing population with more health problems that require tests
  • a shortage of workers in small towns
  • a high turnover of staff means vacancies come up regularly
  • private tests are in demand, such as home DNA tests that need analysing.

Medical laboratory scientist appears on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled medical laboratory scientists to work in New Zealand.

According to the Census, 1,773 medical laboratory scientists worked in New Zealand in 2018.

Chances better for highly skilled scientists

Chances of finding work are best for medical laboratory scientists who have management skills or specialised skills in laboratory technology, and for those willing to work in small towns.

Technology may reduce vacancies

New testing technology may reduce the number of medical laboratory scientist vacancies, however scientists with strong analytical skills will still be needed.

More work in private laboratories and hospitals

Most medical laboratory scientists are employed by hospitals and private laboratory services. 

Other employers include:

  • scientific research laboratories
  • the New Zealand Blood Service
  • universities
  • veterinary clinics.

Progression and specialisations

Medical laboratory scientists may progress into managerial or supervisory roles in a laboratory. With further postgraduate study, they may do research into particular disciplines and scientific methods, or become university lecturers. They may also move into other areas such as teaching, animal health, the food industry, or working for commercial science companies.

Medical laboratory scientists usually specialise in two or more of the following disciplines:

Clinical Biochemist
Clinical biochemists analyse samples of blood, urine, faeces and tissue for diseases such as diabetes and renal failure.
Clinical Immunologist
Clinical immunologists study the body's immune system to test for diseases such as allergies and HIV infection.
Cytogeneticists investigate genetic disease and how chromosomes are affected by disease.
Haematologists analyse blood samples for diseases such as anaemia and cancer.
Histologists prepare tissue samples for investigation by a pathologist.
Medical Cytologist
Medical cytologists test cell samples for cancer.
Medical Microbiologist
Medical microbiologists detect, cultivate and test bacteria and fungi.
Transfusion Scientist
Transfusion scientists prepare blood and blood products for transfusion.
