Police investigating looting during yesterday's quake evacuations say eight burglaries took place and they have stepped up patrols since then.
Detective Sergeant Damon Wells said police were now working closely with the victims to ensure they were supported and understood where investigations were at.
He said officers would attend each burglary and carry out scene examinations. Some of those visits had already taken place.
Wells said police were following positive lines of inquiry.
"The public can be assured that we will be focused on trying to catch the people responsible, especially when they prey on those in such a vulnerable situation in a time of an emergency."
