"As they were already isolating, there is very little risk to the community," Dr Nicholas Jones, the Hawke's Bay medical officer of health, said.
It is not known when they arrived in the Wairoa District. A Ministry of Health spokeswoman said that information would not be disclosed.
"The cases continue to isolate in the Wairoa District [and] there are no locations of interest," she said.
"We do not intend to release any further information about these cases due to privacy reasons."
Of the 106 new community cases, 93 were in Auckland, eight were in Waikato, three were in Northland, and there was one each in Whanganui and Canterbury.
The two latest cases in Canterbury include a close contact of Saturday's case and a young child in the same household. All three have gone to an MIQ facility.
Health officials praised the person whose case was detected yesterday .
"As soon as the person in Canterbury learned of their contact the person got a test and had been isolating at home since that time," the Ministry of Health reported. "The person's prompt actions have reduced the chances of further spread and underline the importance of getting a test immediately if you have been to a location of interest, are identified as a contact or possible contact of a case, or if you have any cold or flu-like symptoms."
There are now 77 cases in hospital, including seven in ICU.
