Calls are mounting for a moratorium on swamp kauri exports amid claims that the trade is illegal and destroying the Far North's fragile wetlands.
The Forests Act 1949 bans the export of swamp kauri logs, many of which are tens of thousands of years old, unless they are made into finished timber products.
Opponents of the highly lucrative trade say exporters are skirting the ban by labelling kauri slabs as table tops, or superficially carving the logs and calling them artworks.
The Far North Protection Society says the government is turning a blind eye to the trade. That is denied by Primary Industries Minister Nathan Guy, who said there was no loophole in the law and the export of kauri logs as Maori carvings was closely monitored.
Society chairwoman Fiona Furrell said some of the carving was little more than "superficial scratches".
