The Police Commissioner has revealed that of the 4547 people who returned to New Zealand over the last three days, 94 of them had symptoms of the coronavirus COVID-19.
Mike Bush said on Monday that of those people who returned to New Zealand, 1200 did not have a satisfactory self-isolation plan so they are in self-isolation managed by the Government.
He said about 3200 did have a plan and they are self-isolating, although the police have a process to visit those people to ensure they are complying with the lockdown restrictions.
Prime Minister Jacinda Ardern said on Sunday that the number of people returning to New Zealand has dropped since the lockdown came into effect, and that the majority are coming from Australia.
Bush also revealed on Monday that three people have been arrested in New Zealand for persistently breaching the lockdown rules, although no prosecutions were laid.
It was also confirmed by the Ministry of Health's Director-General of Health Dr Ashley Bloomfield that 76 new cases of COVID-19 have been recorded in New Zealand, bringing the total to 589.
On Sunday, a woman in her 70s from the West Coast was confirmed as New Zealand's first coronavirus-related death.
