The $2.4m government funded Rena Recovery Plan has now been completed.
Iwi representatives worked alongside government agencies and research providers to deliver on a set of environmental and cultural restoration and research projects over a three and a half year period.
Rena Recovery Group Co-Chair and Ngāti Ranginui representative Carlton Bidois said the aim of the recovery plan was to restore the mauri of the Bay of Plenty environment to its pre-Rena state.
"There's been a lot of passion and hard work gone into delivering the plan objectives. I'd like to thank everyone who contributed their energy, effort and expertise to this kaupapa and to the ongoing recovery efforts," said Mr Bidois.
At the final Rena Recovery Plan Governance Group meeting held last week, iwi and agency representatives heard that no new Rena related oil wash-ups have been reported since March 2014.
