The junior doctors’ union says a decision on the proposed Waikato Medical School is taking too long.

The Ministry of Health is progressing a business case and cost benefit analysis to decide if the $380 million school in Hamilton should go ahead.

It was working with the University of Waikato, which would be home to the country’s third medical school, and Health New Zealand.

The school aimed at producing more GPs to plug dire shortages, particularly in rural and regional areas.

Resident Doctors Association secretary Dr Deborah Powell said it was frustrating a decision had not been made already.
