The seven-day rolling average of case numbers today is 7414, down from 8435 a week ago.
In today's statement the Ministry of Health said there were 466 people in hospital, down slightly from 468 yesterday, with 16 people in intensive care.
It said a person who travelled from overseas to New Zealand has been confirmed as having the BA.4 variant of Omicron - the first known detection of the variant in New Zealand.
"The person arrived in New Zealand from South Africa on 22 April, returned a positive RAT the following day and a positive PCR test on 24 April. Whole genome sequencing was undertaken as part of ongoing border surveillance for emerging variants and subsequently confirmed the BA.4 variant.
"The person followed all testing and reporting requirements, allowing this new sub-variant to be identified quickly, and has been isolating at home."
The Ministry said the BA.4 has been reported in Southern Africa and Europe, and a case was reported in New South Wales a few days ago.
"The arrival of this sub-variant in New Zealand is not unexpected. 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."
The Ministry said there was no evidence to date that BA.4 is more transmissible or causes more severe disease than other Omicron lineages, such as the BA.2 Omicron sub-variant that was causing the "vast majority" of infections in New Zealand.
"It can take weeks or months to identify the severity of each new variant or sub-variant, so the Ministry of Health will continue to monitor the emerging evidence closely."
Two other sub-variants of Omicron - the BA.2.12.1 and the BA 2.12.2 - have also been detected in two returnees for the first time in New Zealand from travellers arriving on 11 and 15 April. The Ministry said neither sub-variant was currently regarded as being of concern.
