Casual contacts should remain vigilant for the signs and symptoms of Covid-19, continue good hand hygiene habits and call Healthline on 0800 358 5453 immediately if they feel unwell.
"Please note you are not required to start self-isolating unless you feel unwell or start to develop Covid-19 symptoms," the Ministry of Health states.
The Health Ministry revealed on Wednesday the three new cases were a family group who flew from Christchurch to Auckland on a September 11 chartered flight after having completed a 14-day stay in isolation.
Christchurch Airport - from where the family flew to Auckland after a 14-day stay in isolation - is also a location of interest:
• Christchurch domestic airport, September 11, 10.30am-12.30pm.
Officials say the infected family has 31 close contacts.
"The three people are part of the same family group – two had been in managed isolation in Christchurch and returned home on the chartered flight, while the third is a household contact. Two were tested because they were known flight contacts of the original case; the third was tested because they were a household contact," the ministry said.
"The family has been self-isolating over the last four days ... the family travelled to Taupō between 18 and 20 September, where they met up with 18 others from five locations around New Zealand. Those 18 people, who travelled from Bay of Plenty, Wellington, Christchurch and Hamilton are all considered close contacts," the ministry said.
"In addition to those 18 people, another 13 people have been identified as close contacts. All 31 contacts have been or are in the process of being tested and all are isolating. Public health services have been in contact with businesses where individuals may have visited while infectious."
Also on the flight was a man who tested positive for Covid-19 at the weekend whose virus is thought to have had a rare three-week incubation period.
The latest cases were seated near the infected man.
There were 86 people on the charter flight. So far 63 have returned a negative test.
Since August 11, 4014 people have been identified as close contacts of cases, of which 4006 have been contacted and self-isolating or have completed self-isolation. The remaining eight people are still be tracked down.
