Labour MP Phil Twyford has tested positive for Covid-19 and will no longer be able to travel to Timor-Leste on Monday.
Twyford is the second Labour MP to test positive today, with Prime Minister Jacinda Ardern earlier revealing she had also contracted the virus.
In a statement, Twyford said he was disappointed he would not be representing the New Zealand Government for the 20th anniversary of Timor-Leste's independence and at the inauguration of Dr Jose Ramos-Horta as Timor-Leste's next president.
New Zealand's ambassador to Timor-Leste, Philip Hewitt, will instead represent the government at these events.
Twyford said he had moderate symptoms and tested positive this morning.
