The Fiji-New Zealand Business Council is urging foreign governments to be cautious about issuing trade sanctions and travel warnings.
Fjii is under emergency rule. Military leader Frank Bainimarama has tightened media censorship and refuses to hold elections before 2014.
Business council Mark Hirst, who is based in Suva, says he understands that other governments will target Fiji's regime.
But he says they need to be careful that they don't affect people who have nothing to do with the military.
New Zealand exports to Fiji are worth about $NZ360 million each year and Mr Hirst says trade sanctions would have a big effect on the economy there.
However, Mr Hirst says limited information is making it difficult to know how businesses are actually coping. He says finding out information is especially hard because New Zealand no longer has a high commissioner or trade commissioner in Fiji.
