Plans to build a landfill that would see 23.4 million tonnes of waste buried in the Dome Valley in North Auckland faced a legal challenge in the Environment Court on Monday, Stuff reports. Waste Management’s lawyer Balthazar Matheson said the new landfill was needed to replace another landfill in north Auckland’s Redvale, which would reach capacity in 2028. Judge Jeff Smith challenged Matheson, asking him whether the landfill as proposed was actually only “stage one of much a larger project”. He also questioned whether its storm water treatment ponds would be able to prevent leachate from draining into the Hōteo River.
