Western Bay of Plenty area commander Inspector Clifford Paxton said it was not possible to draw a correlation between one factor and a rise or fall in Armed Offenders Squad call-outs.
"Police work to a prevention-first model, which focuses on pre-emptively preventing harm in our communities," Paxton said.
"The deployment of the Armed Offender Squad on pre-planned tasks is considered based on a risk assessment of each situation, and is done to ensure the safety of the community and our officers."
Paxton said in general instances, events that the Armed Offender Squad was called to were serious as the members had specific training for prolonged or hostile situations.
However, in some situations, the squad was used as a precaution for pre-planned operations where there was high risk, for example helping other police with search warrants.
"The Armed Offenders Squad provides police with the means of effectively and safely responding to and resolving situations involving an actual or threatened use of firearms against members of the public or police," Paxton said.
"The basic methods of operating are to cordon, contain and appeal to armed offenders.
"These tactics are successful in the vast majority of incidents, which are resolved without the use of force."
