Foreign Minister Murray McCully is considering promoting a law that would allow the Government to impose its own trade and economic sanctions on recalcitrant countries, but he says it is aimed at no one in particular.
Mr McCully, who last night hosted new Australian Foreign Minister Bob Carr at talks in Auckland, said it would bring New Zealand into line with Australia.
Mr Carr's predecessor, Kevin Rudd, who resigned before a failed leadership bid, shepherded the Autonomous Sanctions Act through Parliament last year.
It allows the Government in Canberra to impose its own sanctions by regulation.
Iran's failure to co-operate with the UN nuclear watchdog, the International Atomic Energy Agency, has been cited as a reason for expanding sanctions.
