A yearling for sale at Karaka in South Auckland is expected to fetch a record-breaking price of more than $1 million, organisers say.
Over the six day auction last year, $67 million worth of sales were recorded and the top price paid for a horse was $800,000.
New Zealand Bloodstock managing director Andrew Seabrook told Morning Report he was expecting big interest at the sale starting today.
The colt he is expecting to fetch more than $1m is by the world's highest rated horse, Frankel.
Mr Andrew Seabrook said there had been big demand from Chinese buyers who have imported about 700 horses from New Zealand in the last two or three years.
