As Auckland heads back to alert level 3 and the rest of country into level 2, a top epidemiologist says he fears the government hasn't made the best use of alert level 1.

The area for level 3 is the Auckland Super City boundaries (Wellsford in the north to Pukekohe in the south).
Otago University epidemiologist Professor Nick Wilson says the current state of digital contact tracing is disappointing.
