The Act and National party want former Te Whatu Ora chair Rob Campbell sacked as the chair of the Environmental Protection Authority as pressure mounts on the Government to be consistent.

The Health Minister axed Mr Campbell yesterday, after he penned a public attack on the National Party's Three Waters policy at the weekend.

The former Director General of Health, Dr Ashley Bloomfield, has labelled it a 'rare event'

But Mr Campbell stands by his actions, saying it is core to his beliefs.
