At the time, Zarif had said the traditional exports such as dairy and meat were important but Iran was also interested in technology from New Zealand.
McClay said Zarif had said Iran presented a $1 billion opportunity for New Zealand.
New Zealand had a strong trade relationship which dated back to 1975 when New Zealand established an Embassy in Tehran.
"Iran has traditionally been a very important market for our sheep meat and butter however exports have diminished over a number of years. Since the lifting of UN sanctions there are now renewed opportunities to re-establish this trade as well as new opportunities in the education, construction, food and beverage, energy, forestry, specialised manufacturing and services sectors."
The eighteen New Zealand companies joining Mr McClay on this visit to Iran are: NIG Nutritionals, Tait Communications, Enatel Limited, Sealord, Silver Fern Farms, Westland Milk Products, Fonterra, FrameCAD, Flight Coffee, Switchfloat, University of Canterbury, University of Auckland, ANZCO, Auckland University of Technology, Pacific Helmets, Pelco NZ, NZ Bankers Association, and Pultron Composites.
