The former head of Te Whatu Ora says he didn't do anything wrong in his outspoken attack on the National Party at the weekend.
Rob Campbell was axed by Health Minister, Ayesha Verrall, after he penned a public attack on the National Party's Three Waters policy.
Campbell told Morning Report that it's important that people on Crown entity boards aren't muzzled when it comes to political opinions.
