No new cases of Covid-19 have been found in managed isolation and quarantine (MIQ) facilities or the community, the Ministry of Health says.
With two cases having recovered, the total number of active cases in New Zealand today was 24, the ministry said.
Total confirmed cases were at 2287, after one previously reported case had been reclassified as "not a case" and removed from New Zealand's tally, the ministry said.
The seven-day rolling average of new cases at the border is three, and 60 historical cases - from a total of 471 cases - have been recorded since 1 January.
The ministry repeated its warnings to those who were in New South Wales recently, asking anyone who was at the locations of interest in Sydney at the relevant times to follow NSW health advice, and not travel to New Zealand for 14 days. Such people who were already in New Zealand should call Healthline on 0800 358 5453 for advice about when to get tested.
Restrictions remain around greater Sydney.
Laboratories processed 2738 test on Monday, bringing the rolling seven-day average to 3972, the ministry said.
Three cases of Covid-19 were MIQ facilities yesterday, but none were infectious, the ministry said.
The World Health Organisation is classifying the B.1.617 variant first identified in India as being of global concern, with some preliminary studies showing that it spreads more easily.
Variants first detected in Britain, South Africa and Brazil have had the same classification meaning they require heightened tracking and analysis.
