Prime Minister Bill English has rejected proposals to liberalise drug laws in New Zealand.
English insisted that anti-drug measures were working and said the National-led Government had no plans "to shift the boundary" on drug control.
Associate Health Minister and United Future leader Peter Dunne reiterated on the weekend that New Zealand should move to a Portuguese model for drug control.
Anyone caught with less than seven days' supply of drugs would not be prosecuted, but fined and referred for addiction treatment.
Dunne also wanted New Zealand to move Class C drugs like cannabis from the Crimes Act into the Psychoactive Substances Act, which would allow them to be sold on the open market if they were proven to be low-risk and were sold be licensed people who passed "fit and proper" tests.
