Delta has reached Christchurch, and a snap lockdown has not been ruled out after two unvaccinated people tested positive overnight.
The two are from the same household. One member had recently returned to Christchurch from Auckland.
Covid-19 Response Minister Chris Hipkins told us has been back in Christchurch for up to a week, and unwell for a while, so they could have been infectious during that time.
He also told us the two were not regularly using QR codes.
Christchurch Mayor Lianne Dalziel spoke to Corin Dann.
