Auckland Art Gallery is asking Bay people to look closer at the portrait on their grandparents' mantelpiece or check under the bed in the spare room. They may have a long-lost artwork of one of New Zealand's most celebrated artists.
The gallery is appealing to the public to help find more than about 100 original paintings by prolific 19th-century artist Gottfried Lindauer held in family collections or tucked away in forgotten nooks.
Gallery director Rhana Devenport said Lindauer's paintings were national treasures.
Portraits of Maori chiefs and leaders of the 19th and early 20th centuries remained hugely significant as a record of New Zealand's history and heritage.
The gallery's curator of Maori art, Nigel Borell, said many more paintings had yet to surface and finding the missing artworks would help further research for an extensive exhibition about the artist.
Although some of Lindauer's portraits have perished in fires, some had been given away in disrepair and others had been misplaced.
"We want to piece together the puzzle of Lindauer's prolific painting career to learn more about him," Mr Borell said.
"These Lindauer artworks could be sitting on mantelpieces, in marae meeting houses, forgotten under beds or at grandparents' houses around the country."
He said it would give the gallery a good gauge of just how many portraits still existed. One portrait, known as Heeni Hirini and Child was estimated to have been painted up to 30 times.
Borell said he was aware of 12 versions but would like to find more, to "build a more accurate picture of this fascinating painter".
In 1890 Lindauer settled in Woodville, where he continued to paint until his death in 1926. In 2001, the Lindauer Replica Studio was established in the town.
Last year the the Alexander Turnbull Library admitted it paid $75,000 of public money for a forged Lindauer portrait. It had earlier bought the portrait of Hoani, or Hamiora Maioha, signed "G. Lindauer", at auction.
