The drivers are protesting a decision by New Caledonia's committee for external mining trade not to approve requests to export low grade ore to China, submitted by the territory's veteran mining company SLN and several small miners.
The blockades began two weeks ago and ramped up earlier this week before being eased yesterday for talks between the government and the union representing the small mining entities whom the truck drivers contract to.
The blockades have been fully re-installed today after the negotiations failed to resolve the dispute.
