Duty-free tobacco allowances will be cut from 200 cigarettes to 50 cigarettes later this year, Associate Health Minister Tariana Turia has confirmed.
Next week's budget would also introduce duty taxes and GST for tobacco sent from overseas, which is currently tax-free.
Mrs Turia said youth smoking rates were falling, but smoking still caused 5000 premature deaths a year.
She said it was an anomaly that Government was raising tobacco prices but still offering 10 duty-free packs of cigarettes to every adult who came into New Zealand.
The price differential between duty-free tobacco and retail tobacco was expected to become more pronounced as annual tax hikes kicked in.
