New Zealand First MP Tracey Martin is in self-isolation after potentially coming into contact with the coronavirus COVID-19.
Martin met with Australian MP Peter Dutton last week, and Dutton on Friday revealed he has tested positive for the virus, which has killed at least 5000 people so far.
Martin told Newshub she will be tested on Saturday, but hasn't shown any symptoms so far. She says she didn't shake his hand, but was with him for 90 minutes in Washington DC, where they met with US officials to discuss online child sexual exploitation.
Video footage shot at the meeting shows Martin and Dutton standing shoulder-to-shoulder. The virus isn't believed to be airborne.
Prime Minister Jacinda Ardern has been alerted.
On Friday Canadian Prime Minister Justin Trudeau became the first world leader to self-isolate, after his wife Sophie tested positive for the virus.
New Zealand so far has had only five confirmed cases, and no reported community transmission.
