One of the walking sticks featured Maori carving and paua shell decoration, while another was possibly of Fijian origin and could also be used as a club or staff.
Anyone who purchased the walking sticks and could trace their history could stand to make a significant profit, with all items auctioned with no reserve, Mr Perry said.
Also up for grabs is a Georgian bureau which also belonged to Sir Walter. Found inside the bureau was a letter on Windsor Castle letterhead, although it was difficult to read the name of the sender due to the handwriting, Mr Perry said.
This auction, which includes hand-painted Minton plates, Limoge porcelain, and Royal Doulton character jugs, was "well up there" in terms of the best auctions he had held during his long career as an auctioneer, Mr Perry said.
"It's a long time since I've seen stuff like this and it's become more valuable -- we used to get estates like this every two or three years, now you would be lucky to get one every 10 years.
"It's hard to imagine things coming like this."
The auction items can be viewed in the grandstand area of the racecourse on Sunday between 1pm and 5pm.
The auction starts on Monday at 10am.
Absentee bids will be accepted.
