A Cook Islands select committee looking into grievances over the stalled Te Mato Vai project hopes to have its work back to parliament by August.
The select committee was established to consider grievances and concerns raised by landowners over the huge water supply project on Rarotonga.
It includes four government and four opposition MPs, chaired by the Finance Minister Mark Brown.
He has already said the government had agreed not to charge residential users for their water; that the land would not be taken by warrant and that the water authority would not be privatised.
Mr Brown said there were also some environmental concerns that the water catchment areas be protected.
He said the committee would work to put these concerns in a draft agreement which could then go before the court for ratification to enable the construction to continue.
