On this day New Zealand has reported its 100th day without community transmission.
At present, the country's 23 active cases of COVID-19 have come from arrivals at the border who are in managed isolation facilities.
To date, New Zealand has recorded a total of 1,219 COVID-19 cases since the outbreak began on a global scale.
The country had previously been praised by the World Health Organisation for its effective handling of the pandemic.
The WHO Director-General said New Zealand has shown that COVID-19 "can be overcome through commitment, action and vigilance".
The country's Director-General of Health, Dr Ashley Bloomfield said: Achieving 100 days without community transmission is a significant milestone, however, as we all know, we cant afford to be complacent.
We have seen overseas how quickly the virus can re-emerge and spread in places where it was previously under control, and we need to be prepared to quickly stamp out any future cases in New Zealand.
Every person in the team of five million has a role to play in this."
Towards the end of March, New Zealand was placed into a strict level four lockdown and gradually, restrictions were eased, by entering level three to two and so on.
New Zealand is considered one of the safest locations in the world in relation to the pandemic.
The country continues to urge its five million residents to avoid complacency.
