Those struggling after the violent Valentine's Day earthquake in Christchurch have been assured counsellors are on hand.
Christchurch was rattled by a 5.7-magnitude quake on Sunday that shook the city almost five years on from the devastating tremor that killed 185 and wrought destruction.
GeoNet spokeswoman Anna Kaiser told AAP residents can expect a number of aftershocks in the coming days and scientists say there is a 50 per cent chance of another quake above 5.
No serious injuries were reported after the quake and there were only minor issues with the city's infrastructure.
However a cliff collapsed into the sea near Taylors Mistake, with five young lifesavers narrowly avoiding injury, stock fell from shelves and shoppers were forced to flee malls when the quake hit soon after 1pm.
Christchurch City Council said none of its facilities sustained major damage in the quake.
The council reminded residents and commercial property owners to carry out safety checks to their own buildings, and those affected by liquefaction were advised to take appropriate safety precautions.
Meanwhile, The Ministry of Social Development has reassured residents that quake counselling is available.
Mayor Lianne Dalziel said while the city was in a much better state than it was when the deadly 6.3-quake hit, Sunday's quake did nothing for the nerves.
"It really is a real set-back psychologically for the city," she said.
