The "lighthouse", based on a Mt Eden state house, will be filled with a glowing glass chandelier depicting a coloured glass garden of native flowers, birds and insects.
Documents, obtained under the Official Information Act by the Herald, show artist Michael Parekowhai signed a contract to complete the design work by November last year.
Glass-makers in New Zealand, the United States and Europe are being invited to tender for the chandelier. Parekowhai had pushed for a Venetian crystal chandelier.
Councillors heard that a private individual has made a verbal offer of $100,000 to help meet the $500,000 shortfall and attract other money. The Arts Foundation is also getting involved in fund-raising and a tertiary institute may get students involved in the construction of the house.
Chief operating officer Dean Kimpton said there had been "some frustration" on the part of Barfoot & Thompson chief executive Peter Thompson over the project but the real estate firm was committed to its gift and the project.
Councillor Cameron Brewer said his feedback was that the company had been appalled at the process and hauled over the coals for "a disaster from beginning to end".
Deputy Mayor Penny Hulse said it was "damn right they should be concerned with the process. Not with staff, but the shouting nature of politics".
Councillor Mike Lee said as the sole councillor for the Waitemata and Gulf ward he had not been consulted and wondered how the word "lighthouse" appeared in the update and the words "state house" had disappeared.
Mr Lee was concerned the public had no say in the project on the "people's wharf", while Mayor Len Brown urged councillors to stop relitigating an earlier decision to proceed: "Let's see it through."
