National leader Judith Collins is one of the first MPs to make use of new Parliament rules that allow MPs to travel more freely.
On Thursday, Collins departed for Auckland, currently in stage one of the Government's three-step lifting of alert level 3 lockdown.
Collins, who has been fully vaccinated, will return to Wellington when the House sits again later this month.
She will have to get a negative pre-departure test and isolate for five days following her return, following new Parliamentary rules.
