When you leave New Zealand, you must depart from a place that has a Customs office, unless a Customs officer says you can leave from somewhere else. You have to follow this rule when you are leaving the country. There are some exceptions to this rule, which can be found in regulations.

If you are on a boat or other craft that does not have to stop at a Customs office, then this rule does not apply to you, as stated in section 41(3) and (4). This means you can leave from somewhere else. You still have to follow other rules, though.

There are other rules that are similar to this one, like s 30, which you can look at for more information. These rules help keep track of who is coming and going from New Zealand. They are important for the country's safety and security.
