"All have been referred to police," the spokesman said.

"MBIE and MIQ are not an enforcement agency. It is a legal requirement to have a valid MIQ voucher on arrival in New Zealand, so we provide the details to NZ Police but any further action is at their discretion."
Last November, the Herald revealed altered MIQ vouchers were used by desperate travellers to dodge the MIQ lottery.
One who made simple alterations got him back to NZ and straight into a Rotorua quarantine slot with no questions asked.
"The name, passport number and flight number were all the same. The guy (at the aircraft) scanned it and gave it just a cursory glance," he said.
When he arrived and produced a negative Covid test and passport, he said he was told that he wasn't on the list.
However, the person checking him in handed him a room card, assured him his details would be added manually and that the Ministry of Health would be told.
In the Rotorua case, NZDF MIQ co-manager Brigadier Rose King said what the person did was illegal.
She said the person arrived on October 29 and it was found on arrival that they did not have a valid MIQ voucher.
