Prime Minister Jacinda Ardern's patience appeared to wear thin at interjections from other politicians during a debate over COVID-19 testing.
In Parliament on Tuesday, Ardern was pressed by National leader Judith Collins on why border workers are not having their saliva tested for the virus daily.
Ardern pushed back, saying the Government has begun saliva testing and is researching whether it should be introduced as mandatory for border workers rather than voluntary.
ACT leader David Seymour also chimed into the debate, asking if Ardern was aware of international studies which suggest saliva testing is quicker and equally effective to the more invasive nasal swabs.
The rebuttal from the Prime Minister was that New Zealand has a smaller outbreak, and therefore saliva testing may not yield the same results.
As the line of questioning continued, Ardern appeared to get frustrated with the interjections both from Seymour and from National's COVID-19 response spokesperson Chris Bishop, who called out across the House as she spoke.
"I'm glad there's an expert sitting there on saliva testing, maybe I should bring him into the briefings," she said after Seymour interrupted, as other MPs laughed.
She then extended the same offer to Bishop as he offered his thoughts on the matter.
"Again, Mr Bishop, perhaps you would like to join the briefing with Mr Seymour."
The conversation came as New Zealand recorded a second day of no new COVID-19 infections after three cases were detected in the South Auckland community on Sunday.
Auckland is currently in COVID-19 alert level 3 lockdown as the rest of the country sits at alert level 2. The lockdowns will be revised on Wednesday.
