Prime Minister John Key says he would support Helen Clark making a bid for United Nations Secretary-General if she put up her hand for the job.
But he also played down the prospects of her winning it.
"Those jobs are Herculean tasks to win and there's so much politics at play that it's not straightforward, but in the event that she ran, we would definitely support her," Mr Key told the Herald.
Helen Clark, the former Prime Minister whom Mr Key beat in 2008, is now head of the United Nations Development Programme (UNDP), which means she's No 3 at the UN.
