"So while costs have remained relatively constant over the last two years, income from transactions has dropped dramatically," Mr McKay said.
"The money exchange made a loss of $6291 last year and this year is tracking to double that. The community trust cannot afford to shoulder these increasing losses, which are predicted to continue increasing due to the ongoing use of electronic transfer of funds."
There has been a corresponding drop in the number of transactions processed, he added.
Mr McKay said with the BNZ closing in Wellsford, the closest banks would be in Warkworth, Dargaville, or even Whangarei.
He said businesses in the village would also feel the loss - though an approach late last year to businesses asking if they would subscribe to the service to keep it alive was not supported.
Mr McKay said there was still a possibility the village could have a banking service, after the members of the community approached the BNZ about installing an ATM capable of taking deposits as well as dispensing cash.
He is waiting for the bank's response.
The exchange's last trading day will be Wednesday, June 29.
