Four new cases of Covid-19 have been found in managed isolation and quarantine (MIQ) facilities since yesterday, the Ministry of Health says.
In a written statement, the ministry said two recovered cases meant total active cases was at 102. Total confirmed cases was 2231.
The rolling seven-day average of cases at the border was eight.
Yesterday there were seven new cases of Covid-19 and genome sequencing had shown three infected Grand Millenium workers were directly linked, Director-General of Health Dr Ashley Bloomfield said.
The ministry today said testing was continuing for the 23 contacts of two of those MIQ workers - Cases B and C - and 21 of the contacts had returned negative test results with two results remaining.
The ministry also made note of an update yesterday to locations of interest to include three Auckland bus journeys taken by Case B.
The ministry said the person wore a mask and sat away from other passengers while on bus journeys, so those on the bus were considered casual contacts.
