"Although closely resembling the form of a mutu kaka or parrot snare it could not have functioned to catch birds as it lacks holes for the cord which would be pulled by the hunter when a bird lands on the perch trapping the bird's legs," the auction house said.
"The superb quality of the carving and the elaborate composition would seem to indicate an important ceremonial function which is now unknown."
Also sold at the auction was a rare Maori flute or putorino for $246,000; a wooden hand club from Taranaki which fetched $105,000; a hei tiki reached $17,500; handcarved whalebone short thrusting weapon sold for $47,000; a collection of six pendants went for almost $5000; and a long-handled Maori club weapon was snapped up for $37,000.
Maori artefacts have been hot items with international museums and private collectors in recent years.
A hei tiki fetched $165,290 at Sotheby's in New York in 2008.
In 2014, a rare Maori statue - one of just six known pou whaikairo sculptures in the world - sold at Sotheby's for a world record $2.28 million.
Last year, two ornately-carved Maori statues that once adorned whare gables fetched $160,000 at Sotheby's in New York.
The Ministry of Culture and Heritage monitors auctions within New Zealand, but does not follow those held overseas.
It has no ability under legislation such as the Protected Objects Act 1975 to stop sales, or force repatriation of cultural heritage material sold at auction overseas.
