Kiwis will find out at 4pm tomorrow whether the country will come out of lockdown and move to alert level 3.
Prime Minister Jacinda Ardern made the announcement at this afternoon's daily coronavirus update, accompanied by Director General of Health Ashley Bloomfield.
When asked if we were likely to stay in level 4 for another week until contact tracing is at a gold standard, Arden said: "We are not going to get into hypotheticals."
But Bloomfield responded to a number of questions that have been raised about contact-tracing, saying that the system was being improved to be able to trace 80 per cent of the close contacts from a new case within three days.
There are nine new coronavirus cases in New Zealand and one new death since yesterday, he said.
