An expert says the million-dollar question is how long Auckland will stay in Level Three.

The region moves down a level from midnight tomorrow.

Covid-19 modeller Shaun Hendy says contact tracers have had an epic five weeks, and it's now in their hands to close out this cluster.

He says we'll know in a couple of weeks whether that's worked.

Hendy says the alternative is an extended level three while we wait for vaccine rollout to finish.

He says that will be six to eight weeks from now, and so we'd rather see contact tracers win the day.
