Building and Construction Minister Maurice Williamson was dismissive about the arguments against gay marriage.
"Someone said to me at a meeting the other night, 'Well, this might mean eventually you can end up marrying your dog', and I said again, 'this affects me how?'
"As long as they keep the dog off my lawn I don't care."
National MP for Hunua, Paul Hutchison, on the other hand, will vote against the bill this evening. He said New Zealand's laws were liberal enough. "I've always thought that if Oscar Wilde was alive today, he would think the options available to him, in my view, are quite extraordinarily open.
He added: "I think he would find it pretty good."
Labour MP Damien O'Connor was going against not only his caucus but his own family over his decision to oppose the same-sex marriage bill. His daughter has urged him to change his mind.
"She disagrees [with me] and she comes from an age where there's a different view," he said.
Nearly all MPs at least hinted which way they were leaning yesterday. Transport Minister Gerry Brownlee, however, was giving nothing away: "I don't want to be lobbied. I can't be bothered."
