He said the Bill would also prevent overseas civil unions or gay marriages overseas being recognised in New Zealand.
"My Bill also paves the way for the Government to introduce policies that strengthen and support marriage in New Zealand because of its benefits, not only for couples and families, but for society as a whole.
"It, therefore, amends section 19 of the New Zealand Bill of Rights Act so that it can no longer be considered discriminatory to actively promote marriage - the foundation upon which our society is built," he said.
"As most proponents of the civil union legislation made it clear that they did not want to affect the distinction and sanctity of marriage, I look forward to support from a good majority of Members of this House to send this Bill to select committee."
