A $1 million-plus sculpture of a state house is expected to adorn the Auckland Viaduct - and ratepayers may have to contribute $500,000.
The sculpture, to sit at Queens Wharf, is part of a gift to the city from real estate company Barfoot & Thompson.
But the Weekend Herald understands artist Michael Parekowhai has gone over his $1 million budget. A source told the Weekend Herald the estimated cost had risen to $2 million.
An arts source said Parekowhai - recognised as one of New Zealand's most important contemporary artists - had come up with the concept of a state house located on the northeast edge of the wharf.
A council spokesman said former chief executive Doug McKay agreed to an underwrite of up to $500,000 from the regional public arts budget of $2.55 million this financial year and $1.8 million next year.
