An auction featuring some of this country's most significant artists includes works owned by Eric and Kathy Hertz, who died when their plane crashed into the sea near Kawhia in March.
Among the paintings being auctioned are a 1910 oil of Arawa chieftainess Rakapa by Charles Frederick Goldie, which is expected to bring up to $250,000.
A 1978 acrylic on canvas, considered to be one of Sir Peter Siddell's finest works is expected to bring up to $220,000.
The three paintings in the auction owned by Mr Hertz, the former Two Degrees Mobile chief executive, and Mrs Hertz were by Alvin Pankhurst and expected to sell for more than $100,000 in total, the International Art Centre said in a statement.
The auction is being held at the art centre in Parnell, Auckland next week.
Other well known artists represented at the sale are Ralph Hotere, Sir Toss Woollaston, Gordon Walters, Douglas Badcock, Frances Hodgkins, Peter McIntyre, and Raymond Ching. A 1849 water colour of Auckland's Princes St by Auckland province superintendent Colonel Robert Henry Wynyard was expected to bring up to $35,000. In total the sale could bring close to $2 million.
Sir Peter Siddell's work A Portrait of Tony and Patsy was of the same calibre as one owned by Dame Kiri Te Kanawa which fetched $218,000 last year, centre director Richard Thomson said.
The 1910 Goldie had been in the same private ownership for nearly 70 years.
