National's not ruling out running candidates in Maori seats in this year's election

Labour's pledging to run a vigorous campaign across all seats, as Te Pati Maori and the Greens go through their candidate selection processes.

National ran two candidates in Maori electorates last election, after not doing so for decades.

Prime Minister and National Party leader Chris Luxon says the board's yet to make a call on this year's strategy.

He says they are open to it, but says for them it's very much a party vote campaign.
