On Friday, 18 returnees arrived on board Air New Zealand flight NZ946.
Also on board were two nurses who were scheduled to accompany two medical referrals traveling to New Zealand.
It’s the smallest group of returnees since flights resumed earlier this month.
A total of 138 Cook Islanders and residents have now returned since the easing of border restrictions.
As with previous cohorts, yesterday’s returnees will undergo supervised quarantine in a pre-approved residence marked with a yellow flag for 14 days.
All individuals undergoing supervised quarantine must produce two negative Covid-19 tests before being allowed to join the general public.
The Covid-19 Act 2020 gives the Secretary of Health Dr Josephine Aumea Herman the legal power to order and enforce this supervised quarantine.
Penalties for any breach carry a maximum of 12 months’ imprisonment or a $10,000 fine.
