A Q+A Colmar Brunton snap poll found that that voters are split on whether Judith Collins should step down as a Minister.
But 75 percent of the 500 eligible voters polled said the Oravida saga and Maurice William’s resignation as Minister would not affect who they would vote for.
Mr Joyce told TVNZ’s Q+A programme he wasn’t surprised by the results.
“I mean it wasn't a great couple of weeks but nevertheless what we did see in those poll results, and I think the numbers behind those results suggest, it's actually still, very still on partisan lines, so it's the Labour Greens voters that say the Prime Minister hasn’t done a good job," Mr Joyce said.
"It's the Labour-Greens voters that say ironically that would change their vote, I'm not sure where they will change them to.”

Mr Joyce rejected the suggestion that there was a public perception of cronyism in the National Party:
“It’s just their spin, and I think Russel Norman and Trevor Mallard this last week - and I hope they spend a lot more time on television frankly - because these guys just want to have a mud wrestle, they're not winning the game, they're not winning politics based on the policies and the direction of New Zealand," he said.
They’ve sort of decided they want to have as mud wrestle about donations. And the simple fact of donations is that people give money to the parties whose policies and principles they support. It's true for the National Party, it's true for the Green Party I hope.”
