"It's pretty special being able to tour together but, like any partnership, you need to work to build it," Susannah said.
"We just finished another tour on the circuit leading up to Christmas and it's quite special being able to share these experiences."
The Leydon-Davises will take part in this week's North Harbour International event before heading home to Hamilton for next weekend's Oceania Championships.
Oliver labelled his third Commonwealth Games selection a career highlight, while Badminton New Zealand chief Joe Hitchcock was chuffed for the players.
"Oliver and Susannah make us proud both on and off the court - how they portray badminton and represent our sport is really special to us," Hitchcock said.
The Leydon-Davises' selection takes New Zealand's Games team to 75.
