Queenstown and Wellington are on alert after COVID-19 cases reported over the last few days.
Passengers on a jet boat ride operated by Shotover Jet Queenstown on 2 January, between 9am and midday, need to isolate until they return a negative test result, the Ministry of Health said.
It confirmed that the passengers are regarded as close contacts of the positive case.
The resort town's Skycity Casino, Oaks Suites hotel, and the Shotover Jet building are locations of interest over the New Year period.
The person who has since tested positive stayed at the hotel from 30 December until 2 January.
They also visited the casino between 5:50pm and 7:30pm on New Year's Day.
People at those locations during those times have been asked to look out for any symptoms of COVID-19.
Testing in Wellington almost doubled to 800 yesterday after two cases and seven locations of interest popped up on Saturday.
A third person from Wellington who attended the Britomart Block Party in Auckland on New Year's Eve has also tested positive.
Anyone who attended this event between 11.15pm on 31 December and 2.30am on New Year's Day should get tested immediately and look out for symptoms for 10 days after the exposure.
The Ministry of Health said the person is in isolation and, at this stage, no locations of interest have been identified in the Wellington region.
There were 27 new community cases of COVID-19 and 33 in Managed Isolation and Quarantine (MIQ) facilities reported today.
