There are 5656 new cases of Covid-19 in the community today – and another six people with the virus have died. 

And a person who travelled from overseas to New Zealand has been confirmed as having the BA.4 variant of Omicron. It is the first known detection of the variant in New Zealand. 

The person arrived in New Zealand from South Africa on April 22, returned a positive RAT the following day and a positive PCR test on 24 April. 

The Ministry of Health released the latest numbers just after 1pm. 

There are 466 people in hospital, including 16 in intensive care. 

The variant was confirmed by whole genomic sequencing, which was done as part of ongoing border surveillance. 
 
The arrival of the sub-variant was not unexpected, the ministry said, having already been detected in Southern Africa, Europe, and in Australia a few days ago. 

"At this stage, the public health settings already in place to manage other Omicron variants are assessed to be appropriate for managing BA.4 and no changes are required." 

There was no evidence to date that BA.4 was more transmissible or causes more severe disease than other Omicron lineages. 

The release of today's data came after seven new Covid deaths and 7043 community cases were reported on Saturday. 

On Saturday there were 468 people in hospital with the virus, 15 of them in intensive care. 

This was down from the highs of 1016 people in hospital on March 22 and 33 people in ICU on March 21. 

The deaths took the total number of publicly reported deaths with Covid-19 to 744. The seven-day rolling average of reported deaths was 11. 

In terms of case numbers, Saturday's seven-day rolling average of 7413 cases continued a steady decline from the peak of 20,467 on March 8. 

However, the decline has slowed somewhat, the seven-day rolling average only dropping from just over 8000 two weeks ago. 

While the overall case trend is declining, parts of the South Island, including the West Coast and South Canterbury, are experiencing an uptick. 

Earlier today, Associate Health Minister Ayesha Verrall announced new, more accurate Covid Lamp tests, which return results in 30 minutes, will be trialled at Auckland Airport. 

The Lamp (loop-mediated isothermal amplification) tests can be self-administered like an RAT (rapid antigen test), but are much more accurate. 

They will be trialled at the airport, initially limited to 30 Air NZ staff, and could eventually be used in hospitals, aged care and other sectors. 

The announcement was made as New Zealand's border fully reopens for the first time in more than two years to international visitors from visa waiver countries at midnight tonight.
