The French Polynesian group seeking lower fuel prices has rebuffed a goverment offer for talks.
The President, Oscar Temaru, had invited the leader of Te Tau no te Hono for talks today to discuss its grievances.
However, in a letter to Mr Temaru, the group leader, Francky Tehaamatai, says it has to decline the invitation as it is preparing a rally outside the territorial assembly on Saturday.
Mr Tehaamatai says the group leaders will then be available for discussions.
Last month, Te Tau no te Hono mobilised an estimated 2,000 people for a march in Papeete as part of its campaign to have the latest fuel price hike rescinded.
The rally came after the group, using trucks and heavy machinery, blocked some Papeete roads for three days, causing massive traffic jams.
There has been no indication that the government of Oscar Temaru will authorise a fuel price drop.
