Labour MP Grant Robertson has "categorically" ruled out challenging his party leader before next year's election.
Speaking on The Nation today, Labour's finance spokesman said leader Andrew Little had his full support, despite ranking poorly in a recent Newshub preferred-prime minister poll.
"The guy that I work with everyday is working hard," he said.
"He's got the vision to say we need to focus on health, education, housing, building up jobs around New Zealand and I think he's doing a good job."
He would "categorically not" challenge Mr Little, he said.
Mr Robertson ran in a party leadership race against Mr Little in 2014, narrowly missing out on the top spot.
