The Auckland Council are "wimps" for not acting more quickly to save Waitakere Ranges' endangered kauri trees, says National MP Judith Collins.
She and other senior Labour and National MPs would like access to the ranges restricted to help save the trees, which are being threatened by kauri dieback, an incurable fungal-like disease spread by people and animals.
Kauri dieback had doubled in the Waitakere Ranges in the past five years, and is now threatening the kauri to the point of extinction, according to scientist and Unitec Associate Professor Dr Peter de Lange.
De Lange chairs the New Zealand panel on what species should be on the IUCN red list, the international list of plants facing extinction.
"Because of the rate of decline that's been mapped and because we have good data, that kauri is now being listed as a threatened species," he told Radio NZ's Morning Report.
