With the increased number of Tasers on the hip of officers, the chances of them falling into the wrong hands increase.
Police say that is not a concern but on Christmas Day 2012, in Dargaville, two police officers were severely assaulted and had their own Taser fired at them during a street brawl.
Tasers were first used in Northland in 2010, when 42 of the 50,000-volt shock-bolts were introduced.
The lightweight handheld Taser delivers a jolt of electricity through a pair of wires into two silver probes, propelled by compressed air from up to 7 metres away.
The jolt stuns the targeted person by causing an uncontrollable contraction of the muscle tissue.
Police statistics for 2014 show there were a total of 36 incidents where a Taser was used.
In 29 of those cases offenders were "laser painted" - where a red laser beam is pointed at the target and only in one case did a Taser discharge probes.
Pepper spray, handcuffs, a police dog, baton and firearms were other options police can use to diffuse situations.
Northland police operations manager, Inspector Marty Ruth, said the incident of the officer assaulted in Dargaville in 2012 was rare, and police were confident security arrangements around Tasers were robust. "Any use of force by police will always be dictated by the situation at hand and the behaviour and actions of those who confront our officers or the public. When used appropriately, the Taser has proven its effectiveness in keeping the public, offenders and police safe," Mr Ruth said.
Dargaville-based Senior Constable Ewen Cumming, during sentencing of Joshua Mohetaue, described the horrifying moments when he saw his police colleague attacked during a Christmas Day brawl.
" I thought he was dead and had been killed by the group. The feeling of helplessness and distress cannot be adequately described."
While attending to his injured colleague, he was shot at with a Taser.
Mohetaue was jailed for five years after a jury found him guilty of injuring with intent to cause grievous bodily harm.
