Deputy Prime Minister Grant Robertson is unconcerned by a poll showing the Government's popularity plunging.

The most recent Roy Morgan poll has seen the Labour Party drop 6.5 points since late May.

But Robertson denies it's a reflection on the Government's latest policies and ideas - like potential hate speech reforms.

Robertson told Heather du Plessis-Allan Labour isn't here to mind the shop, and intends to put in place the manifesto it campaigned on.

"I tend to think that people see these things in the whole. I've just done a big, long tour around New Zealand post-Budget, and I see an economy that is going much, much better than people expected."
