Daily saliva testing is being done in conjunction with PCR tests at high-risk sites, Prime Minister Jacinda Ardern says, and the government is considering rolling it out further.

Read back through live Covid-19 updates for Monday 15 February:
The Ministry of Health said investigations were continuing into the three cases, and as a result the number of locations of interest, close and "casual plus" contacts could change.
The ministry said high levels of testing was expected in Taranaki, where some of the three community cases had visited. Locations included Taranaki Base Hospital; MediCross Urgent Care & GP Clinic; Hāwera Hospital; Waitara Health Centre and Ōpunake Health Centre/Coastal Care.
They said the high demand could mean delays at testing sites, and asked people to be patient. People who were not at one of the listed locations at the stated times did not need to be tested if they were not symptomatic.
