Grant Robertson says he acted in the best interests of New Zealanders throughout his career.  

The politician delivered his valedictory last night, saying he's proud of the Covid response.  

He also said it had been his honour and privilege to be a minister but wishes he could've changed the tax system.  

Robertson told Mike Hosking that he gave 100 percent.  

He says he fronted up and explained why they were doing what they were doing, and he understands why people may disagree but doesn't get the hate.
