Dr Ashley Bloomfield is confident Auckland is getting on top of stamping out its Delta outbreak.
Auckland moves down to Alert Level Three tonight.
Daily case numbers in the region remain in the double digits.
But the Director-General of Health told Mike Hosking almost all of those cases are household contacts of existing cases.
"Those are actually, for a Delta outbreak in a big city, very low numbers. In both Victoria and New South Wales they've still got really significant restrictions in place, and they've got numbers in the hundreds."
