What are the chances of getting a job?

Chances of getting work as a radiation therapist are average because:

  • only around 30 radiation therapy students a year are accepted for training
  • many radiation therapists leave New Zealand to get experience overseas
  • an ageing population increases demand for more health checks and scans for age-related diseases

However, medical radiation therapist appears on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled radiation therapists from overseas to work in New Zealand.

According to the Census, 1,209 radiation therapists worked in New Zealand in 2018.

Most radiation therapists work for public hospitals

Most radiation therapists work in hospital oncology (cancer) departments in:

  • Auckland
  • Hamilton
  • Palmerston North
  • Wellington
  • Christchurch
  • Dunedin.

Radiation therapists may also work in private cancer treatment centres in Auckland, Tauranga, Wellington and Christchurch.
