There are currently no Customs charges for travellers going out of New Zealand.
Departure taxes are imposed at some airports and may already have been built into your ticket price. You should check for any charges with your travel agent.
When you leave New Zealand there are only a few charges that you may incur for goods you might be sending out of the country.
If you are shipping or freighting goods such as personal effects, gifts, unaccompanied baggage and pets, they will need to be cleared by Customs. Goods under $NZ1,000 can be cleared by electronic cargo information. Goods over this amount will need to use an export entry clearance.
Shipping companies or freight forwarders usually do this clearance on your behalf and add it to your fee; so you may not need to worry about submitting it yourself. The only thing you might need to do is itemise correctly the goods you are sending.
If you do clear your goods with us personally, find out how much the appropriate clearance will be at Customs charges, duties and allowances
