National continues to push for laws that make life tough for gangsters in Western Australia to be applied in New Zealand, despite acknowledging its policy may infringe on Kiwis' rights.
National's police spokesman Mark Mitchell told the Q+A show this morning that Western Australia used non-consorting laws and dispersal notices which could be emulated.
"It's putting enormous pressure on the gangs to the point where gangs now are coming out publicly and saying 'it's just too tough for us' and they're moving across the borders and into other states."
Mitchell told the TV1 programme that police using such laws could disperse gang gatherings, and gangsters who failed to comply could be arrested.
"I can promise you ... these drive-by shootings are organised."
Lawmakers in WA last year passed legislation banning the display in public places of gang insignia.
If caught showing gang colours in public, members of 46 alleged WA gangs can face up to a year in jail and fines between roughly NZ$13,000 to $67,000.
However, Mitchell admitted National's policy may be a contradiction to the New Zealand Bill of Rights Act (BORA).
He said an assessment was yet to take place to determine if the BORA would be infringed on by the party's proposals.
Section 17 of the BORA grants New Zealanders the right to freedom of association, while section 18 refers to the right to freedom of movement, and section 14 of the legislation is the right to freedom of expression.
"On the Bill of Rights it's as simple as this ... gang members steamroll and trample over the rights of everyday Kiwis on a daily basis," Mitchell said.
"They put them at enormous harm, they're discharging high-powered military rifles through people's homes, and actually if they continue to act like that then they're going to have to understand that there's going be some tough legislation that may impinge on some of their rights."
He said Kiwis were waking up daily to news of gang shootings and the only question was not if or when there'll be another shooting, but whose street it will be in next time.
"It's unsurprising that as gang membership has exploded, there's been an escalation in crime, including public intimidation and shootings."
Luxon said crime and increasing gang membership had complex causes and in the long run, National would help steer at-risk young people in a prosocial direction.
But he said before that social investment approach could pay dividends, there was an urgent and immediate need to tackle gangs.
Luxon said a National-led Government would stop gang offenders associating with each other, and would stop gang members accessing guns.
National pledged to give police power to issue firearms prohibition orders against any gang member who in the previous 10 years was convicted of a serious offence.
Police Minister Poto Williams last week said Australia had better gun laws, compared with lax rules in New Zealand.
