Criticism continues this morning about the government's Covid-19 messaging in the wake of Aucklanders breaching isolation rules.

Pasifika Medical Association chief executive Debbie Sorensen said official terms such as "casual plus contact" were hard to grasp.

And Manukau councillor Efeso Collins said popular social networks such as TikTok should be in the mix to reach young people.

However, Auckland Mayor Phil Goff did not believe prosecuting rule-breakers in the Papatoetoe Covid cluster would achieve much.

The mother of the latest community cases had gone for a walk with the mother of another family identified in the cluster during a level 3 lockdown.

Police said they had not begun an investigation into the rule breach. They need information referred to them from the Ministry of Health, which they have not yet received.
