An examination of whether 17-year-old criminals should be kept out of the adult justice system has the support of Labour.
Justice Minister Amy Adams has asked officials to examine if steering 17-year-olds to the Youth Court - instead of treating them as adults as is currently the case - could cut rates of re-offending.
Labour leader Andrew Little said the party supported an examination of the issue, and he personally felt a change should be made.
"At the age of 17 the young adult brain is still not fully developed. And I personally doubt whether it is a good idea to put offenders at that age into the adult criminal justice system.
"The main objective must be, even at that age, people have to be rescuable, if you like. We've got to have faith that we can stop teenagers from going on to harder criminal offending. And the best way to do that is to keep them out of the adult criminal justice system."
