Parliament on Wednesday voted 77 to 44 to legalize same-sex marriage, which will make New Zealand the 13th nation in the world and the first in the Asia-Pacific region to allow gay couples to marry. The bill was supported by Prime Minister John Key, who is on the center-right. The new law will allow gay couples to jointly adopt children for the first time and allow their marriages to be recognized in other countries. The law will take effect in August.
