New zealand states

I think you meant to say "New Zealand regions" or "New Zealand provinces"! New Zealand is divided into 16 regions, which are further divided into 67 territorial authorities (districts or cities). Here are the 16 regions:

1. Auckland Region
2. Bay of Plenty Region
3. Canterbury Region
4. Chatham Islands Region
5. Gisborne Region
6. Hawke's Bay Region
7. Manawatu-Wanganui Region
8. Marlborough Region
9. Nelson Region
10. Northland Region
11. Otago Region
12. Southland Region
13. Taranaki Region
14. Tasman Region
15. Waikato Region
16. Wellington Region

Note that some of these regions are also referred to as provinces, but technically, New Zealand does not have provinces in the classical sense. The regions are more administrative and geographic divisions, while the provinces are historical and no longer have any official status.
