Local police have welcomed the almost $300 million national investment in emergency services.
Police Minister Stuart Nash said today new investment would see an unprecedented push to disrupt organised crime and make our families and communities safer.
Budget 2018 includes $298.8m in new operating funding and $17.8m capital for the police over the next four years.
New Zealand Police Association regional director Scott Thompson said any investment into policing was welcome.
"For police any investment from Government has a positive impact.
"Better health and education alleviates the calls for service from police."
Additional funding will also be provided for victim support services, community law centres and the Independent Police Conduct Authority.
Over the next four years $13.4m will be spent to increase the age of people who can be dealt with in the youth justice system to 17.
A total of $57.6m has been set aside with the aim to reduce New Zealand's prison population by 30 per cent over the next 15 years.
