A Christchurch supermarket will reopen in days after urgent earthquake repairs were ordered following new engineering reports.
Countdown Northwood announced on Thursday evening that the supermarket had been closed suddenly for urgent strengthening.
Countdown managing director Dave Chambers said the supermarket had received engineering reports late on Thursday afternoon indicating that urgent strengthening work was needed.
The company had decided to close the store immediately to be "absolutely certain'' that the store was safe, he said.
"We acknowledge that this will be an inconvenience but the safety of our customers and team is our first priority and we will not compromise that.''
Chambers said the supermarket would work closely with its landlord during the repair process, which could take "a number of days''.
Supermarket staff would be given work at other stores in the area, he said.
Northwood Supa Centa owners AMP Capital said no other buildings at the shopping centre had been closed.
Property portfolio general manager Stephen Costley said strengthening work was being completed on one wall at the Countdown supermarket, and the store was expected to reopen in the next couple of days depending on available resources.
The urgent work had been needed following "more detailed" engineering assessments on buildings at the centre, as requested by the Canterbury Earthquake Recovery Authority.
Work to fix cosmetic damage at other parts of the centre was ongoing, but no stores had closed during the repairs, he said.
"I'm comfortable we have no other issues at the centre," he said.
