A justice reform group is calling for 17-year-old offenders to be dealt with by the youth justice system rather than the adult criminal courts.
JustSpeak, a network of young justice system activists, called for the change in a open letter to Prime Minister John Key and senior justice sector ministers Judith Collins, Anne Tolley and Chester Borrows.
The open letter was signed by 150 people at the group's annual camp at Pipitea Marae in Wellington today.
There were about 10,000 apprehensions of 17-year-olds last year, so the change could make a difference to thousands of young people every year.
JustSpeak spokeswoman Lydia Nobbs said they could not vote, buy alcohol or tobacco, or enlist in the military without consent - but offenders were treated as adults within the criminal justice system.
