NZ Coronavirus cancellations

Hi, New Zealand has just had a 14 day self isolation imposed on all travelers arriving into New Zealand from 1am tomorrow morning, including NZ travelers.  I am not sure if this is deemed to be a quarantine or not.  Our self contained room has no cooking facilities, and is not suitable for self isolation purposes so I would like to cancel the bookings that I have thus far.  Does anybody know if I can do this under the Coronovirus rules?
