The Caledonia Together Party has defended its statement on Facebook which prompted two politicians to quit a 10 member leaders group.
Their post referred to a weekend meeting of the group which reportedly agreed to propose 4 November as the independence referendum date.
The party said all ten leaders present agreed on the date and on accompanying statements, including one which said colonisation brought with it the negation of the Kanak people.
Sonia Backes, who quit the group, said for her the expression of regret is too strong.
Caledonia Together said the words are taken from the 1998 Noumea Accord.
The group, dubbed G10, was set up at the behest of the French prime minister Edouard Philippe to discuss the aftermath of the independence referendum.
Its task is to hold discussions in confidence under the leadership of the French High Commissioner.
The other politician to quit the group is Thierry Santa who is the president of the Congress and a senior member of the anti-independence Rassemblement.
The Caledonia Together Party said Ms Backes and Mr Santa were pulled out by their respective parties under the pretext of being upset over the Facebook post.
The pro-independence politician Victor Tutugoro said talks will continue with those who want discussions.
