Two legal firms are preparing a class action lawsuit that could end up being the country's biggest environmental claim.
North South Environmental Law in Auckland, assisted by Holland Beckett Lawyers in Tauranga, has identified 150 claimants affected by the Rena grounding - and expects to add more in coming weeks.
The claimants, all business owners, will become part of a joint lawsuit to bring proceedings against Greece-based Rena owner Daina Shipping Co.
Individual claims from Bay businesses currently range between $20,000 and $250,000.
The class action is understood to be the biggest negligence-based environmental claim in New Zealand, only outdone in size by class actions against finance and investment companies.
