There are more confirmed cases of Covid-19 in Christchurch.
The Ministry of Health has just confirmed there are now four active cases in the city.
The virus has also been detected in Christchurch's wastewater on October 27.
In total there are 125 new community cases across the country, including 118 in Auckland, four in Waikato and one in Northland.
"The rise in case numbers is a reminder of the infectiousness of Covid-19 and particularly the Delta variant, and the importance of vaccination as the best protection," said a Ministry of Health spokesperson.
"With over 30,000 tests processed nationwide yesterday, these results aren't unexpected."
It was revealed yesterday that two people from the same Christchurch family had returned positive Covid-19 tests.
One of the pair had travelled from Auckland on October 15 - with an exemption related to essential childcare - and infected a second person in their household.
The first case returned a negative test before coming to the South Island but later became unwell.
Covid-19 Response Minister Chris Hipkins said both are both unvaccinated and had "not been particularly good users of the Covid tracer app".
It is mandatory to sign it at most places around New Zealand either using the app or manually providing details.
The Minsitry of Health was notified about the positive cases on Wednesday night but did not release any locations of interest until after 2pm on Thursday.
There are currently 13 locations of interest in Christchurch - a list that could be added to later today when more information is released by the Ministry of Health.
Anyone at the locations at the specified time should self-monitor for Covid-19 symptoms for 14 days after exposure.
If symptoms develop, get a test and stay at home until you get a negative test result AND until 24 hours after symptoms resolve.
The first 13 locations confirmed yesterday are:
• The Mad Dairy on Main South Rd, Hornby: 12.45pm to 1.15pm, October 18
• Hornby Chinese Takeaways on Main South Rd, Hornby: 12.45pm to 1.30pm, October 18

Yesterday the Canterbury District Health Board said its testing centres were already experiencing increased demand.
"And we have increased capacity to respond to this, with additional staff brought on board," said CDHB senior responsible officer for Covid-19 response Dr Helen Skinner.
"Our Orchard Road site will remain open late today as demand requires.
"Please get tested if you visited a location of interest or have cold and flu symptoms."
