A Don Binney painting has sold for more than half a million dollars at auction this evening, making it the most expensive Binney work ever sold.
The large piece - La Chute d'Icare, Pureora: Last Flight of the Kokako - was valued at between $300,000 and $500,000.
It sold for $455,000, or $534,625 including a buyer's premium of 17.5 per cent.
It is part of the Warwick and Kitty Brown collection of modern art, with all 300 pieces being auctioned this evening and tomorrow through Mossgreen-Webb's.
Binney - who died in 2012 - was famed for his paintings of birds.
The 1979 oil painting of a kokako in flight was painted as a fundraiser for an environmental group, in response to concerns about logging threats to the bird's habitat.
As well as the Binney work the auction included artworks by Colin McCahon, Tony Fomison, Pat Hanly and Ian Scott.
Nearly 100 lots sold this evening at a total of more than $2,200,000.
Other paintings sold tonight include a Fomison at $117,500, a huge price for the artist.
Warwick and Kitty Brown started collecting in the mid-1960s, picking up works by their friends and contemporaries.
After Kitty died last year Warwick Brown decided to sell the collection as a way to "memorialise [the] marriage".
Brown's favourite work in the collection is Own Drum by Don Driver.
The work had an estimated worth of $6000 - $8000 but sold tonight for three times its original estimate - $21,000 plus buyer's premium.
