Managed isolation and quarantine data

Data and statistics about managed isolation and quarantine in New Zealand.

Find our daily snapshot data below. We changed the format of these on 30 July 2021. The snapshot now includes the impacts of cohorting on capacity.

We have combined occupied rooms and rooms unoccupied due to cohorting, to create a total room allocation that more accurately reflects room availability.

Previous reporting from May to end of July

Our daily reports from May to the end of July did not explicitly show the impacts of cohorting on capacity. During this period, the reports showed a gap between our operational capacity of 4,000 rooms per fortnight and the rooms allocated. A large proportion of these rooms could not be filled due to cohorting requirements. As a result, this suggested rooms were available in MIQ when in fact they were not able to be allocated.

Cohorting

The new variants of the virus, and continued outbreaks overseas, have meant we’ve had to adjust our approach over time.

In order to significantly reduce the number of infected people flying to New Zealand, at the end of April the Government introduced a new ‘very high risk country’ category. Cohorting was also introduced at the same time, based on public health advice.

People arriving in New Zealand over a 96-hour window are now taken to MIQ facilities until they are full or the 96-hour period is over. The facilities then close their doors until the end of the cohorting cycle, with no additional returnees allowed in until after the last of the cohort have completed their stay and the facilities have been cleaned. A cohorting cycle can be between 18-20 days – this accounts for the 4 days of infill, the 14 days isolation for the returnees and 1-2 days to clean before the next cohort.

This ensures returnees are in the same facility as others who have arrived at about the same time, and prevents any cross infection from recent arrivals to people who are about to leave.

If the facility isn’t full at the end of the 96-hour period, then those rooms go unused and unoccupied until the end of that 18-20 day cohorting cycle.

Flight schedules play a vital part in the filling period – if there are no flights, or flights are cancelled, this has a significant impact on occupancy, and more rooms are unoccupied. MIQ does not have any control over flight schedules or flight cancellations.

Contingency

MIQ’s usual operating contingency to allow for unexpected events is 400 rooms a fortnight. When quarantine-free travel was introduced with Australia, an additional 500 rooms per fortnight (on top of our usual contingency of 400) were set aside, resulting in an operating capacity of 4,000 rooms.

Managed Isolation rooms allocated

As at 10:00AM 22 October 2021

The below graph illustrates projected room allocation. “Total Rooms Allocated” is defined as occupied rooms plus rooms unavailable due to cohorting. Please see the explanatory notes on the MBIE website which provide further explanation about the information contained in this daily snapshot, especially around the rationale for introducing cohorting into our managed isolation facilities. The projections are updated once a week on Fridays.

MIQ key updates

MIQ had an operational capacity of 4,500 rooms per fortnight prior to the establishment of Quarantine Free Travel. When quarantine-free travel was announced, 500 rooms per fortnight were set aside as contingency to manage any potential changes to quarantine-free travel. This decreased the overall MIQ operational capacity to 4,000 rooms a fortnight. Additional factors also affect our operational capacity at any one time. These include:

  • the ongoing maintenance and ventilation programme which sees facilities shifting in and out of our available capacity as remediation work is completed; and
  • MIQ introduced a cohorting system to further reduce risk of in facility transmission in May 2021 based on public health advice. The introduction of cohorting has meant that after 96 hours, we are unable to continue to fill a facility which leaves some rooms unavailable for a period of time. On average, cohorting is projected to reduce room availability by 15%.

Community outbreak

Community members are entering facilities to quarantine and isolate to aid in the Government’s response to containing the current outbreak of COVID-19. Stopping the spread of COVID-19 and ensuring a return to a lower alert level as soon as possible is a priority for all New Zealanders.

We have updated the daily snapshot to include the number of quarantine rooms being utilised. This includes both border cases (recent arrivals) and community cases. Note: this number will be different to the number of people in quarantine, as more than one person can be in one room.

We have reconfigured some facilities to maximise usage for quarantining, which has impacted capacity. The situation is evolving at a rapid pace and as such, MIQ is continuing to evaluate capacity.
