The last major painting by New Zealand artist Charles Frederick Goldie described as a "rare national treasure" is expected to sell for more than $1 million.
A Noble Relic of a Noble Race was Goldie's last significant work, painted in 1941 before he died aged 76.
The painting is of Maori chief Wharekauri Tahuna and will be auctioned at Parnell's International Art Centre next month.
The centre's director Richard Thomson said the artwork was one of the painter's best.
"This is a national treasure and not many works of art deserve that title. This does.
