The Ministry of Health has recorded another seven cases of the Omicron coronavirus variant at the border in the past 48 hours.
There are now 45 cases of the highly transmissible variant in New Zealand.
Ministry of Health data released on Sunday shows 10 COVID-19 cases have been detected at the border in the past two days - seven of which are Omicron.
The Omicron variant, first identified in South Africa, continues to run rampant across the world but has yet to leak into New Zealand's community.
COVID-19 infections have soared wherever the highly infectious variant has found a foothold, including in Australia and the UK, triggering new record numbers of cases.
Omicron is becoming dominant in much of Europe including in Britain, where new daily infections have soared beyond 100,000.
Meanwhile, the latest community case count in New Zealand was 126 in the past 48 hours. The ministry said the infections were in Auckland, Waikato, Bay of Plenty, Lakes, Taranaki and Northland.
