Finding teachers to teach specialist subjects at school has long been a challenge.
Late last year the Bay of Plenty Times reported Bay secondary schools were facing an ageing workforce and difficulties recruiting maths and science staff.
A Post Primary Teachers' Association report highlighted nationwide issues, including difficulty finding maths and science teachers.
The difficulties were particularly the case in maths, science and technology. It was hard to attract staff in those areas because they could get higher paid jobs in other industries, PPTA Bay of Plenty chairwoman Rae Brown said.
People who specialise in those areas study for years to become qualified so it's understandable that they would choose lucrative careers in the industry over teaching.
