Water Management Act 2000

If a member of a private water trust sells to a person land to which the trust provides or is able to provide water supply or drainage services—

the member ceases to be a member in respect of that land when that sale takes effect, and

the purchaser is taken to be a member of the trust when the sale takes effect, and

the purchaser has all the entitlements and liabilities of the vendor as a member, in respect of the land, that the vendor had immediately before the sale took effect.

A member of a trust who sells land as referred to in this section must notify the trust of the sale in accordance with any requirements of the regulations or the rules.
