New Zealand Labour says it will keep raising foreign aid should it win Saturday's election, but advocates have urged Jacinda Ardern's government to give firm timelines.
Foreign affairs has been a little-discussed area of the election campaign, expected to be won handsomely by Ms Ardern.
The opposition National party hasn't issued foreign policy, while Labour quietly issued a nine-paragraph policy as part of its manifesto on Tuesday afternoon.
The manifesto is short on specific promises but does commit Ms Ardern's party to increasing Official Development Assistance (ODA) to 0.7 per cent of gross domestic product; it currently gives 0.3 per cent.
David Parker, Labour's foreign affairs spokesman, said New Zealand's Pacific neighbours would receive more aid following the COVID-19 pandemic.
"We take our manifesto commitments seriously," he told AAP.
"If we think New Zealand and Australian economies have been affected by COVID, and they definitely have, well the effects are more severe in the Pacific. They need our help."
Oxfam New Zealand executive director Rachael Le Mesurier said that wasn't good enough.
"We absolutely must see a clear timeline ... a weak commitment to 'make progress' on a target we have failed to meet for half a century is not enough," she told AAP.
"We need to step up with the resources to support our neighbours."
Mr Parker said Labour won't set targets, saying "we're happy to stand on our record of increasing aid and we promise to do it again".
Trans-Tasman relations are unlikely to be affected by the election result, with both Labour and National committing to no radical post-election changes.
However, there is likely to be a new foreign minister, with Winston Peters' New Zealand First party likely to miss out on a return to parliament.
Likely contenders for the role are former leader Andrew Little and Mr Parker, though the decision is Ms Ardern's, and she has refused to speculate on it.
Mr Parker said Australia was New Zealand's most important relationship "bar none".
"We have a very warm relationship," he said, despite the thorny issue of deportations - which Mr Parker said no side of NZ politics could fix.
"That does raise a sense of injustice in New Zealand which is why the prime minister continues to raise it forcefully," he said.
