Labour leader Andrew Little will do a "slight rejig" of his caucus this week after Clayton Cosgrove's decision not to stand next year, but has ruled out changing key personnel such as finance spokesman Grant Robertson.

Little said he had no plans to replace Robertson or make any significant changes to his line-up after TVNZ Colmar Brunton poll had Labour at just 28 per cent.

"There will be some slight rejigging in the next week or so, but I'm not anticipating any significant changes." There was speculation former finance spokesman David Parker could get the finance role back, but Little and Parker denied it had come up.

Little said nobody had suggested he change the finance spokesperson, and when he set up his Shadow Cabinet in 2014 he made it clear Robertson would be in the finance role until at least next year's election. "I'm totally satisfied with Grant's performance and have no intention of changing him out of the finance role."


Parker ruled himself out for the finance role during the 2014 leadership contest, which he took part in.

Little said the poll was "disappointing" but had not spooked him or the caucus. "We are struggling to get clear messages through on our priorities. We've got to work harder at that."

Meanwhile, Puketapapa Local Board member Michael Wood has put up his hand to be the Labour Party's next candidate for the Mt Roskill seat in Parliament.

The father-of-three said having served the community on the local board for the past six years, he knew what the electorate needed.
