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 says 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.
