His wife Christine says they've already raised $47,000 for the lodge, and have about 40 promised cull cows to come.
But Mrs Gibson is keen for the scheme to spread further within the Waikato and Bay of Plenty regions.
"If we can keep it going we will have the debt paid off. They're paying interest on that all the time, which is money which could be better spent on helping the facility to run," she says.
For those city-slickers wondering what a cull cow is, farmers send a small percentage of cows to the works at the end of the milking season, Mrs Gibson explains.
"At the end of the milking season when all the cows are dried up a farmer will go through the herd and say 'she's at the end of her milking life, she's not a good producer, or she's got something wrong with her,' you've got to make room for young stock coming in.
"We've got a farm here with 450 cows and at the end of the season we send away about 20-30 cows."
The farmers tag the cows with a special pink tag, and when the cows go through the works the money is automatically diverted to the Cancer Society. As much as $800 can be raised for each cow.
She says it is a "fairly easy" way for rural communities to raise money.
"Most farmers, particularly the bigger farmers, wouldn't notice the money from one cow when they've sent away 20 or 30. It's not like we're drawing money out of their account.
"And so many people down here know someone who has used the facility."
