The Marriage (Gender Clarification) Amendment Bill was voted down the other night. Tony Milne has a good personal summary of the speeches and events in the House.
Below is voting record of MPs (there's one vote short on the Maori party - I understand because of proxy issues rather than a formal abstention):
