Health Minister Andrew Little is being accused of spending too much on reform, rather than access to healthcare.

The country's 20 DHBs warned the Government a year ago of "critical workforce issues", calling it an "unsustainable situation".

They wrote to the Ministry of Business Innovation and Employment, warning some overloaded hospitals were at "code red".

National Party Health spokesperson Dr. Shane Reti told Mike Hosking the minister failed to act on warnings from the sector.

He says the letter's gloomy prognosis has now come true.
