Suva: Fiji's rugby union chiefs promised to press ahead with the international sevens rugby tournament next month, despite mounting pressure to isolate the country following the military coup.

"Our plans have not changed," Fiji Rugby chief executive Timoci Tavanavanua said.

"We are in the process of writing to all the invited teams to reassure them that this tournament will continue as planned and that the safety of players and officials would not be in danger," he said.

Fiji, the reigning world sevens champions, has not hosted an international sevens tournament since a previous coup attempt by George Speight in 2000.

The New Zealand government, one of the first to impose sanctions on Fiji after Tuesday's coup, said it will hold discussions with sporting organisations scheduled to attend tournaments in Fiji.

New Zealand has already banned Fijian sports teams from entering the country unless required to under international sporting obligations, a decision which has angered opposition parties.

The Greens and United Future parties want Fiji barred from the New Zealand round of the International Rugby Board sevens series in February if a democratic government is not restored in Suva by then.

"Sevens Rugby means a lot to Fiji and being allowed to participate in the Wellington tournament will be used by the regime as recognition of its legitimacy," United Future leader Peter Dunne said.
