Getting paid the right amount of money and paying tax is important when you work in New Zealand.

Tax (IRD number)

Before you get a job in New Zealand, you will need to have an Inland Revenue Department (IRD) number. Your IRD number is unique to you and its purpose is to ensure you are paying the right amount of taxes. An IRD number is required to get a job.

You'll need:

your passport details.
your most recent overseas tax number (if you have one).
your Immigration New Zealand Application Number (from your visa letter).

You can learn more about IRD numbers and how to get one here.

Kiwi Saver

If you get a job in New Zealand you may be asked to sign up for KiwiSaver. KiwiSaver is a government-run savings account that is open for New Zealand citizens and residents and helps them prepare for retirement or other big financial costs. International students are NOT eligible for KiwiSaver - so be sure not to sign up or your paycheck may be smaller than it should be with no benefit. If you become a New Zealand Resident, then you can look into whether KiwiSaver is right for you. More information can be found here.
