A TVNZ One News Colmar Brunton poll shows nearly two-thirds support for same sex marriage.
Asked if they think same-sex couples should be able to get married, 63% of respondents said yes, 31% said no and 6% did not know or preferred not to say.
The Catholic church remains staunchly opposed to gay marriage.
“The whole idea of marriage seems to be associated with the procreation and raising of children and that’s a relationship that requires a man and a woman,” said Patrick Dunn, the Catholic Bishop of Auckland.
Carey Baptist College vice principal Laurie Guy said on TV ONE’s Close Up on Wednesday evening that while it is not inevitable, quite likely Christians will just have to accept gay marriage.
