Prime Minister Jacinda Ardern has finished her meeting with former US President Barack Obama at Government House.

The meeting between the 44th US President and Ardern went into overtime - it was supposed to last half an hour but is just winding up now after 50 minutes.

Ardern said Obama spoke of the welcome being a real highlight, acknowledging the whale tooth he was gifted.
