Here are some links to the same sex-marriage debate in New Zealand.
The first link is to a member’s bill on the New Zealand Parliament website. From the right hand menu on this page you can read the debate notes for the first reading and the evidence presented to the select committee.
The Marriage (definition of Marriage) Amendment Bill is in the name of Labour MP Louisa Wall.
The MP submitted the bill to a ballot of member bills and it was drawn on 26/7/2012. The first reading was held on 29/8/2012 and was passed 80-30 (conscience vote) to be referred to Government Administration Committee – a cross-party select committee of MPs which will examine the bill, listen to submissions (submissions were due 26/10/2012), and report back to the House by 28/3/2013. The committee may recommend amendments which are voted on during the second reading. If it passes the second reading the bill then goes to the committee of the whole House (all MPs) when MPs can put forward further amendments in the form of Supplementary Order Papers. The 3rd and final reading is then held and, if passed, the bill is then given royal assent.
Incidentally, Prime Minister John Key has said he will support the vote through all stages.
