Ms Clark said the Crown entered into this agreement because as the salvage costs mounted it feared the shipping company could become insolvent or walk away from the negotiating table.
There would be a substantial cost saving to Rena's owners if the wreck was left on the reef, but by entering into $10.4m agreement the Crown had secured a share of those savings for the people of New Zealand, she said.
Ms Clark said the Crown the always intended to consult with iwi during the resource consent process, and had not yet decided its position in terms of the resource consent.
Motiti Rohe Moana Trust spokesperson Hugh Sayers begged to differ. Mr Sayers said the Crown had been "dishonourable and dishonest" in its dealings over the Rena grounding.
Mr Sayers said the Crown's dishonesty included it claiming it did not know who to consult while Crown law officials sat alongside Motiti iwi in an Environment Court appeal hearing in early 2012.
"The conduct of the Crown throughout since the Rena grounding has been dishonourable, and I say dishonest," he said.
Mr Sayers said the bottom-line was that wreck must be removed and the environment restored.
The inquiry continues today.
