Prime Minister Jacinda Ardern is backing the design of a managed isolation facility at the centre of a Covid-19 outbreak.
Tuesday marks six days into a nationwide alert level 4 Covid-19 lockdown, and as of 1pm on Monday there were 107 cases associated with cluster.
The case has been traced back to the Crowne Plaza hotel, but it is not known how it got from the hotel to the community.
Police are looking for people who used an atrium near the facility, that was separated from the managed isolation using a perspex barrier, on Saturday 7 August.
Ardern told Morning Report investigations are underway, but she is happy with the way the facility was designed.
"Everything that we've done around our managed isolation facilities has been based on the way that we know Covid-19 has been behaving."
The Crowne Plaza has been closed regardless to investigate further how the infection made it out.
"Just in case we do find that it has come out through some other means that we have not yet identified that means that we can address that immediately."
