After 102 days with no reported community transmission, a family of four in South Auckland, New Zealand tested positive for COVID-19 on 11 August.

The family did not have any known link to overseas travel and was not in managed isolation.

And why is that surprising? To know that, we have to delve into recent history.

Past Successes

Previously, New Zealand is one of the countries in the entire world which managed to come the closest to stamping out Covid-19 within their country.

They employed one of the most effective counter Covid-19 strategies decisively and went into a lockdown relatively early.

On 23 March, the total number of infections in New Zealand was 102.

That day, Prime Minister Jacinda Ardern ordered the country to move to Alert Level 3 immediately, (something like Singapore’s Phase 1).

48 hours later, the country was on lockdown at Alert Level 4.

Citizens received an emergency text message from the government with all the measures of the lockdown clearly laid out.

“We have a window of opportunity to stay home, break the chain of transmission, and save lives,” says Prime Minister Jacinda Ardern. “It’s that simple.”

During the month-long lockdown and the subsequent transition to Alert Level 3, New Zealand managed to reach a stage of no new infections.

Eventually, on 8 June, the last remaining COVID-19 patient recovered. The number of active COVID-19 cases in the country to zero, an amazing feat.

Imported Cases

Following the good news, New Zealand moved to Alert Level 1, where restrictions are largely lifted though border control stayed.

However, on 16 June, two new imported cases from the UK were reported.

As the number of flights to New Zealand increased, so did the number of active cases, though the situation was contained.

There were no community cases still, and all the cases were under managed isolation.

On 12 June, the number of active cases was 25, and the numbers stayed low all the way till August when the community cases restarted.

New Waves in the Community

We arrive back at the present, where the family in Auckland tested positive.

At noon of 12 August, Auckland was moved to Alert Level 3 until Friday, 14 August, while the rest of the country moved to Alert Level 2.
