Both their fathers served in World War II, and Brendon Deere's uncle Alan Deere was New Zealand's most famous World War II fighter pilot. He flew in the Battle of Britain.
"We do it because we want to do it. It's something that people seem to enjoy seeing every year. We get very good feedback from it," Brendon Deere said.
This year's flypast will be a proper ANZAC event. One of the pilots is Australian Alex Joel, a qualified flying instructor on exchange from the Royal Australian Air Force.
Squadron leader Sean Perrett will fly the Spitfire. It was restored nine years ago, after being used by Britain's Royal Air Force (RAF) during World War II, then the Italian, Israeli and Burmese air forces.
The other Texan air trainer will be flown by Flight Lieutenant Dan Pezaro.
The Spitfire is one of several old aircraft at the Biggin Hill Historic Aircraft Centre, on the Ohakea base. The centre is named after a RAF base Alan Deere flew out of during World War II.
