In conversations with Sophia Smedley, owner of Kaikoura Bakery, Mr Mackwood said they had discovered some interesting links.
"We found out not only that Sophia's husband's mum, and Rochelle's mum went to school together in Oamaru, but his sister is here in Whangamata on holiday and plans to come in to see us tomorrow."
The Smedleys have two children - one at university and another working as an apprentice in the bakery so the money raised would be a help to them.
He said they had not expected their project to attract so much media interest.
"We're the same sort of town as Kaikoura - one road in and out - and it's just heartbreaking for them to be cut off from their everyday trade. It makes you stop and evaluate life."
As word spreads, Mr Mackwood is expecting tomorrow's trade to be as busy as a Labour Weekend Saturday.
"If that happens we'll be stoked. We'd be happy if we get $5000 but I've got a feeling we'll go past that."
So, instead of getting to work at 3.30am tomorrow, Mr Mackwood will be up and baking at 2.30am. Aside from the pies which are bought in, the couple and their staff scratch bake everything.
"We'll be pulling in extra staff - they're all amped about it and keen to help."
