The water claim has been brought by several claimants and each claims to be representative of others similarly affected. There are 13 claimants in the statement of claim but others have since been added as further case examples. The claims began in 2008 through resource management proceedings affecting the hapū associated with certain hot and cold water springs. They grew to include case examples from other hapū and iwi covering the full range of water body types.

The claimants strive for inclusivity. They recognise that they are but case examples of others similarly affected. They recognise that any question of whether some hapū and iwi are affected by earlier settlements is for those hapū and iwi to resolve.
