Labour endorses New Zealand's campaign for a temporary seat on the United Nations Security Council in 2015 - 2016.
Prime Minister John Key announced the bid in a speech at the UN on Friday, in a speech covering a range of international issues, including climate change, nuclear disarmament and the global recession.
An election for the seat will be held in 2014.
Opposition foreign affairs spokesperson Chris Carter says Labour can support the bid during international travel meetings with ministers in other countries.
New Zealand is a founding member of the United Nations and previously served on the Security Council in 1954, 1965 and in 1993.
