That group, along several others have called for community-based justice processes to maximise rehabilitation instead of a punitive approach that sees prisons become more and more full.
Labour leader Jacinda Ardern said the law and order policies of the past had failed.
She wants Northland's Te Ara Oranga programme - where police and health partner to help problem meth users - to 4000 more people in regions high-use areas including the East Coast and the Bay of Plenty.
It would cost $38 million over four years.
"It reduces supply through targeted enforcement, and reduces demand by steering drug users into recovery and treatment programmes and helping them find work," Ardern said.
The programme was piloted under the previous National-led Government, in was given an extra $4 million in Budget 2019.
The programme has seen referrals to treatment rise from 24 to 611 between December 2017 and June 2020, arrests increase from 9 to 195 people, and 95 people were supported into new jobs.
It puts Labour and National both on a similar path in terms of wanting to reduce meth-related harm.
National has previously announced plans for at least one specialist worker and a meth-detox bed in every DHB, and a $50 million contestable fund for new or scaled-up programmes to reduce harm.
Asked about how cannabis laws are disproportionately applied to Māori, Ardern noted the drug law changes last year that codified police discretion to refer someone to health services instead of prosecuting them for drug use.
"We've only just seen the beginnings of that legislation, but what we will be keeping a close eye on is the way that's rolling out.
"We want to keep seeing that it is evenly applied."
A Herald investigation found that it has led to fewer prosecutions and more use of warnings and alternative justice processes, but more Māori were prosecuted in recent months for cannabis use when compared with non-Māori.
Labour's justice spokesman Andrew Little has previously announced a new alcohol and other drug treatment court for Hamilton when the Safe and Effective Justice group's report landed last year.
Today he said another one would be set up in Hawke's Bay, costing $11m over four years, to be running within a year.
Labour also wants a special programme to help Māori women prisoners, who make up 68 per cent of the women's prison population. It would cost $10m over four years and be developed alongside Māori, starting in Christchurch Women's Prison.
There is no specific number commitment to boost the police force but Labour wants to keep the ratio of officers per population to 1:500.
It also wants a more diverse police force.
NZ First wants 1000 new officers.
