"He didn't know he was nominated."
"I didn't tell him because I knew he'd just say 'don't be daft'.
"He doesn't do what he does here for recognition, but now he knows how much the team know and appreciate all the hard work he does.
Mr Francis was humble in accepting the award, which he was only told he had won after the event.
"I suppose it's nice to be recognised," he said.
"But it's more about the recognition for Pukaha than for me.
"We're doing some amazing things there and it's great to be a part of it."
The nomination for the award read "Bob doesn't work on the front line of conservation.
"He's not out there weeding, building aviaries, hosting visitors or caring for the birds.
"But he is the powerhouse behind the all important money, which allows the staff and volunteers to do all those things.
"He's led the Pukaha Mount Bruce Board to fund and build four stages of capital improvements worth over $4.8 million since 2008.
"This has allowed tens of thousands of visitors to engage with and understand conservation values and view conservation in action at Pukaha Mount Bruce - and they take those values and messages with them."
The annual award that Mr Francis won is funded by the Gibbs Wildlife Conservancy and is for 'Services to Conservation in New Zealand'.
The conference was in Rotorua on July 22 and 23.
