Thirteen new cases of Covid-19 were confirmed yesterday, with 69 of the 71 active community cases being traced to the Auckland cluster.
All but essential travel out of the city is banned.
A police spokesperson says they've dealt with three people at Auckland Airport trying to fly to Dunedin, and on Monday had to remove a woman from a plane bound for Christchurch.
They warned several of her family members who were also planning to travel - and alerted the airline.
