The tiny building planned as a precursor to the Hundertwasser art centre opens today in Whangarei.
He Kakano - the seed - was blessed by kaumātua in a dawn ceremony this morning at the city's Town Basin marina.
The spiral structure known as a folly was designed to give local tradespeople some practice in Hundertwasser-style building techniques.
It has been approved by the late artist's foundation in Vienna.
The completion of the artwork will be celebrated with speeches, school choirs, kapa haka and a solo performance by Whangarei National MP Shane Reti.
