Mr Simpson said Wanganui-based international boxing judge Bob Gibson, who organised the event, was handling the donation.
"Mr Gibson has taken the cheque, and it's going now," he said.
Part of the delay was deciding which Christchurch charity the money would be donated to.
This week it was decided that the money would go to the Earthquake Appeal Trust.
The donation, however, does not include the interest accrued on the $30,000 that has been sitting in the bank since the fight last December.
Mr Simpson was unsure what the money made from interest would be used for.
"We'll decide what to do with it in due course," he said.
Mr Simpson would not confirm how much interest had been accumulated on the money but did indicate roughly how much interest it was getting in the trust bank account.
"You only get about 3 per cent at the bank," he said.
Mr Simpson said they would be calling for applications in Wanganui to decide where the $5000 set aside for local charities would go.
"That's the fairest way of doing it," he said.
He said they would hopefully advertise for charities on Saturday.
When asked why it has taken so long for the money to be donated, Mr Simpson said there was no reason for the delay.
"No particular reason. We just wanted to make sure everything was done correctly," he said.
The other $10,000 raised will remain in the bank as working capital for the next charity fight.
Mr Simpson was unsure when this fight would take place.
"We haven't decided, but it's going to be midway next year."
Next time the money raised would just be donated to Wanganui charities, Mr Simpson said.
"We're going to try and assist the town."
