Labour leader David Cunliffe's standing by the way his party's selected its candidates.

It comes as Rangitata candidate Steve Gibson has again labelled National MPs "shylocks" and Selwyn candidate Gordon Dickson has written a letter to a political journalist accusing them of cowardice, political bias, and laziness.

Mr Cunliffe doesn't think Labour's made a mistake and tried to field too many electoral candidates and run short of talent as a result.

"No, I wouldn't say that.

"I think we've got a great list and a great party and I've got total confidence in the president and her ability to handle those matters."
