What are the chances of getting a job?

Shortage of medical laboratory scientists

Demand for medical laboratory scientists is high due to:

  • an ageing population with more health problems that require tests
  • demand for new types of laboratory testing due to greater scientific understanding of biological processes.

Medical laboratory scientist (cytoscientist) appears on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled medical laboratory scientists from overseas 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

Demand is particularly high for medical laboratory scientists who:

  • have experience managing laboratory teams
  • have specialist knowledge in laboratory technologies due to technological advances in diagnostic laboratory testing and analytical instrumentation
  • specialise in cytoscience as genetic technologies are rapidly advancing and there is a shortage of workers.

Types of employers varied

Most medical laboratory scientists work for 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/Cytoscientist
Medical cytologists/cytoscientists 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.
