They will feel justified after two below-average days of sales in Christchurch, where disappointingly only one lot - by Gotta Go Cullen - reached $100,000.
The Christchurch sale was always going to struggle, with the problems in the region, stakes issues at Addington and several key buyers not even attending.
Many of the regular top spenders at the sales will come to Auckland with few new yearlings already purchased so expectations are high for today's sale.
There are good reports about Lot 67, a Christian Cullen colt from former classy filly Fight Fire With Fire who is expected to be one of the stronger lots of the week.
"We are definitely expecting this to be the big day of the week," says Rachel Deegan, from auctioneers PGG Wrightson.
"We have more Australian buyers coming to Karaka than Christchurch and more South Islanders coming up too, including some buyers who never usually come to Karaka.
"So we are expecting this to be a good sale."
The sale starts at 11am.
