Omicron has peaked in Canterbury with cases expected to decline slowly over the next few weeks.
Canterbury District Health Board chief executive Peter Bramley made the announcement on Monday.
"I think we can safely say that we are now coming down from the peak, and it will be a slow steady decrease over a number of weeks," he said.
"As I've said before, and will say again, it's not over. This is a time to remain vigilant with mask wearing, staying home if you're sick, RAT testing if you have symptoms, and keeping up with all the good public health habits that help keep us all safe."
In mid-March, it was revealed the CDHB area had the highest number of active community cases in the country.
