Managed Isolation and Quarantine (MIQ) has released about 1000 fewer rooms this morning than initially planned because of the Omicron variant of Covid-19.
Instead of 3100 rooms going online at 9am, officials cut capacity to 2050, citing a "rapidly evolving situation" with the new strain.
The rooms were available between December and March.
An MIQ spokesperson said there needed to be enough room for international arrivals as well as community cases in coming days and weeks.
