A change in method is bearing fruit for police in Canterbury.
Despite a slight increase in overall crime for the start of this year, the crime rate's been steadily dropping over the past three years in the city.

"We've put quite a bit of work in relation to how we actually respond to them now so that's a combination of the initial response but also putting a prevention team providing advice very shortly afterwards."
Todd says last year there was a spike in armed robberies of liquor outlets and dairies, but the two groups responsible have been caught.
