Specialise in Environmental Health for your Bachelor of Health Science at Massey

The environmental health major of Massey’s Bachelor of Health Science (BHlthSc) is designed to give you the training needed for a professional career in human health protection. You’ll learn how to protect people and communities from threats to health from our built and natural environments.

What is environmental health?

Environmental health is the professional area concerned with all aspects of the environment that may affect human health.

Threats to human health may be biological, physical or chemical. They may come from natural processes, human activity, or a combination of the two. You’ll study topics such as:

  • food safety
  • infectious disease transmission
  • drinking water quality
  • urban air pollution.
  • the hazards of excessive noise
  • exposure to toxic and other hazardous substances,
  • workplace monitoring
  • medical geochemistry
  • contaminated site assessment
  • waste management
  • climate change.

What isn’t environmental health?

In the health context, environmental health does not mean the health of the wider environment – for that you would study environmental science. However, there is a complex range of inter-relationships between the two areas. Climate change is a good example of an environmental impact that will have major direct and indirect impacts on human health.

Further study

You may wish to consider further study once you have completed your degree such as a Postgraduate Diploma in Health Science or Master of Health Science.

A Bachelor of Health Science in Environmental Health is a good fit if you:

  • would like to play a key role in community health protection
  • like communicating with people from a diverse range of backgrounds
  • are comfortable with applied science and love a challenge.

Planning information

If you study full-time, you’ll take eight 15-credit courses each year.

Make sure you include courses that are prerequisites for the next level of courses you wish to study.

Course planning key

Courses that need to be completed before moving onto a course at the next level. For example, a lot of 200-level courses have 100-level prerequisite courses.
Courses that must be completed at the same time as another course are known as corequisite courses.
Some courses are restricted against each other because their content is similar. This means you can only choose one of the offered courses to study and credit to your qualification.

Careers and job opportunities

With a Bachelor of Health Science majoring in environmental health, you’ll be ready for a wide range of careers. Most jobs in environmental health involve working with people to promote a healthier environment in which to live. Two key occupations are: health protection officers (HPOs) with district health boards and environmental health officers (EHOs) with local councils.

Here are some examples of the types and fields of work that await you:

  • Central government – Ministry of Primary Industries; Ministry of Health; Environmental Protection Authority: technical advisors; policy analysts; programme managers.
  • Local government – health protection officers or environmental health officers; public health advice, food safety/Food Act compliance; building inspection; liquor licensing work; resource consenting; disaster management and emergency planning; waste management; water quality management.
  • Private sector – consultancies and industry; food quality assurance; workplace and environmental safety; waste management; food safety auditing; environmental quality assurance.

In the future, many of the health issues that concern us at the moment will take second stage to environmental health problems. These include climate change, an upsurge in the frequency of severe weather events, the depletion of natural resources, challenges in maintaining food security, mass migrations, the spread of zoonotic diseases (COVID-19 is only one example) and increasingly polluted air, soil and water. These are going to make the next century especially challenging for economic and socio-political systems and human civilisation as a whole.

Professionals in this area are increasingly sought after. In New Zealand these include:

  • Environmental Health Officers who work with local authorities, and
  • Health Protection Officers who work with District Health Boards.
