Looks like CHC may be gearing up for more international travel.
I am currently serving day number 5/14 of quarantine in Auckland. Customs have just notified me that they are busy arranging a charter flight for those who's home is in the South Island and that a new quarantine facility in Chirstchurch has been opened. Auckland is probably reaching capacity quickly and with the add of the Tokyo service to AKL and the SQ service to CHC it was only a matter of time.
This would be a great start to getting Aussie travellers in to the South Island much quicker if more flights are being established and the bubble is approved
