The country's managed isolation facilities are now fully booked until after Christmas.
There has been an increase in people coming home for the holidays and as of this morning more than 32,000 people had secured a place.
Since Tuesday, travellers have been required to have a voucher for a bed in a facility before boarding an international flight to New Zealand.
A managed isolation spokesperson said there were no vouchers available now until Boxing Day, and facilities were operating at capacity.
