"In addition to creating economic opportunities, we hope that efforts to progress the nuclear deal will create a window for Iran to reset its relationship with the international community."
However, a Ministry of Foreign Affairs paper on the lifting of sanctions says while Iran provides economic opportunities for New Zealand it will be challenging.
"An opaque regulatory environment, weak commercial law and IP protection, very high tariff levels and problems with corruption mean that New Zealand companies looking to do business in Iran will need to do their homework."
It warns businesses to get legal advice before moving in Iran.
There has been a series of sanctions on Iran since 1979, including asset freezes, banking sanctions and trading sanctions throughout the 2000s after Iran refused to halt its uranium enrichment programme. A breakthrough deal was forged last year between Iran, the five Permanent Members of the Security Council and Germany. New Zealand was the president of the Security Council at the time the deal was endorsed by the council.
In January, the International Atomic Energy Agency reported that Iran had taken the measures agreed to under that deal, opening the way for the lifting of most sanctions.
