The star of the show, however, was the 119-year-old surveyor's map of Greytown, contributed by Mr Regnault, which had been in his family for four generations.
The map, drawn by surveyor Thomas McKay Drummond, sold to a Greytown developer for $5000.
"The map's going to stay within the community, which is great," Mr Regnault said.
"It was a bit of a heartstring puller for us to see it go, but it's going to a fantastic cause."
Also going under the hammer was a bat crafted by the Greytown branch of Fearnley Cricket Shop, and signed by the 1982/83 New Zealand cricket team - including Sir Richard Hadlee and Jeremy Coney. The bat sold for $1000.
Mr Regnault had estimated the cost of his wife's treatment, which she will receive in Singapore, to be around $200,000.
The family has been told she will start the treatment in February next year. "We've got a bit of time to raise the last bit of cash," he said. "For now, we're going well - just putting one foot in front of the other."
