The Ministry of Health's locations of interest list for the three new Auckland Covid-19 community cases has grown by three.

The new locations are BP Papakura, GAS Piopio and BP Breakwater Road in New Plymouth.

The new active community cases reported on Sunday are a mother, father and daughter from Papatoetoe.

Details of the new cases were revealed at a Beehive press conference fronted by Covid-19 Response Minister Chris Hipkins and director-general of health Dr Ashley Bloomfield on Sunday afternoon.

The father is a self-employed tradesman and the daughter is a high school student at Papatoetoe High School, which will be closed Monday and Tuesday.

The mother works at LSG Sky Chefs in Mangere, one of the world's largest airline catering providers.

At this stage, Hipkins said there were still "gaps in our knowledge" around the new cases.

For example, the source of the contraction is a "piece of the puzzle" that is needed, as well as whether it virus has been spreading.
