Flights, airports, supermarkets, and the Sky Tower are among new locations of interest linked to the confirmed community Omicron cases.

Nine cases from a single family have been confirmed as having the Omicron variant, Prime Minister Jacinda Ardern confirmed on Sunday.

The cases have triggered a move to the red setting for the entire country, Which came into effect from midnight.

The family travelled to Auckland from the Nelson/Tasman region on 13 January, attended a wedding and other events and visited a theme park and the Sky Tower (on 16 January, from 10am to 11am). They then returned to the Nelson/Tasman region on 16 January.
