An iwi leader is suing the government over its "failure" to act fast enough on climate change.
Climate change iwi leaders group chair Mike Smith, from Ngā Puhi and Ngāti Kuri, made the announcement he was taking the government to court at today's release of the Interim Climate Change Commission report.
Mr Smith said he wanted the government to declare it would halve greenhouse gas emissions in the next decade, and eliminate them by 2050.
