Labour Party President Nigel Haworth has rapped party delegates over the knuckles, telling them a lack of discipline and internal bickering hurt the party and made it look amateurish.
Mr Haworth delivered his address to the Labour Party conference in Palmerston North this morning.
He spoke of the party's defeat in 2014 and the need to make sure it was focused on winning in 2017.
To do that, Labour needed to have discipline and focus in everything it did, he said.
However, Mr Haworth said the delegates too had to play their part.
