More managed isolation vouchers will be released for April and May over the next few days.
Managed isolation and quarantine officials stopped re-releasing people's cancelled vouchers at the start of the month, as the Pullman Hotel was gradually emptied of returning travellers.
The vouchers were kept for contingencies as authorities investigated COVID-19 transmission at the hotel.
Now some new dates are being released in small batches to avoid a system overload.
Five cases of the South African strain of COVID-19 were linked to the Pullman, after a Northland woman tested positive for the virus after leaving the facility.
The most recent case was reported in Hamilton on February 6, after another former Pullman guest tested positive a week after leaving the hotel.
CCTV is being installed at the Pullman and its ventilation system, suspected of being a factor in the outbreak, is being upgraded.
The Ministry of Health hasn't yet said when the isolation hotel is likely to resume operation.
