Iran's foreign minister is visiting New Zealand as part of a push to renew relations following the lifting of sanctions.
Mohammad Javad Zarif will meet with Foreign Minister Murray McCully on Sunday and with Prime Minister John Key on Monday.
The landmark Iran nuclear deal brokered last year has paved the way for the lifting of United Nations sanctions, which New Zealand formalised last month.
That means Kiwi businesses are once again able to trade with Iran.
At the time, Mr McCully said New Zealand's embassy in Tehran is being bolstered to help develop trade and other high-level exchanges planned for later in the year.
Iran was New Zealand's fifth largest export market before UN sanctions were imposed in 2006.
Dr Zarif is visiting New Zealand as part of an 11-day diplomatic mission to six countries in south-east Asia and the Pacific.
