Local iwi are dismayed three Rena recovery iwi liaison roles have been scrapped and claim the move came without warning.
The roles were disestablished this year as part of the central government's decision to reduce the overall resources allocated to the Rena Long-Term Environmental Recovery Plan.
Iwi and local authorities agreed to work together under the plan to restore affected beaches, seabeds, waterways, and fisheries to their pre-Rena disaster state.
Rena Recovery manager Bruce Fraser said late last year a review of the long-term recovery plan was undertaken to look at resources, including staffing.
Mr Fraser said the review process was undertaken in consultation with a number of different people including iwi, and as a result the decision was made to reduce staffing levels.
