Police in Christchurch say a high security presence, including assistance from the Army, has contributed to a relatively low level of crime in the quake-damaged central city.
Regular police patrols are continuing, along with checks of documentation in the cordoned off areas of the CBD.
Superintendent Andy McGregor says that's resulted in relatively few instances of dishonesty offending, or reports of inappropriate access.
Mr McGregor is urging motorists to continue to take extra care when driving anywhere around the city.
He says people should be mindful of how unstable many roads and bridges could be, and vehicle speeds and weights need to be kept down to avoid further damage.
