No, it's just that there's some kind of amnesty where new migrants can bring in funds from their 'home' country tax-free for 4 years. It doesn't mean you can work tax free in NZ, unfortunately. I'll have to find something on this to post on here.
OK,
here it is .
Just a snippet, as there's more in the link........
Temporary tax exemption on foreign income for new migrants and returning New Zealanders
From 1 April 2006, people becoming tax residents in New Zealand may qualify for a temporary tax exemption on some of their foreign income. This temporary tax exemption is available to those who qualify as a tax resident in New Zealand on or after 1 April 2006 and are new migrants or returning New Zealanders (transitional residents) who have not been resident for tax purposes in New Zealand for at least 10 years prior to their arrival in New Zealand.
The exemption can only be granted once in a lifetime.
The exemption
The temporary tax exemption for foreign income is for four calendar years (up to 49 months). The exemption starts on the first calendar day of the month you qualify as a tax resident in New Zealand and is valid until the last calendar day of that month four years later. For example:
You qualify as a tax resident in New Zealand on 22 April 2006 and have one or more types of foreign income that are temporarily exempt for taxes in New Zealand (see list below). You are eligible for the exemption counting from 1 April 2006 until 30 April 2010, which effectively is 49 months.
