A majority of (New Zealnd) voters support changing the law to allow gay couples to adopt children, according to the latest Herald-DigiPoll survey.
Labour and the Greens have pushed the rights of gay people as an election issue, but the National Party has sidelined them as not a priority.
Adoption in New Zealand is governed by the Adoption Act 1955, and Labour and the Greens say the law needs of an update.
More than half - 54.3 per cent - of the poll respondents said the law should be changed to allow gay couples to adopt children, 38 per cent disagreed, and 7.7 per cent did not know or refused to answer.

Green MP Kevin Hague, who has started a cross-party group to find political consensus on gay issues, said the result was pleasing.
"It's great to see that most New Zealanders now support this, and I'm confident that once it's in place, that majority will increase even more.
"What should be at the centre of adoption laws is putting the interests of the child first. To do that you've got to have all the options on the table."
