"Overseas, table tennis is really big. I was in Copenhagen with my dad and there was just a streak of table tennis tables lined up. It became a way of engaging with the locals.
"It's done so well overseas. But here, people tend to just use parks to run around rather than spend time in."
The group got hold of three table tennis tables and ran "Ping Pong Park" events in Western Park, Ponsonby.
"We chose it because there's a lot of foot traffic," says Marieke, who has been involved in staging Music in Parks and Movies in Parks with the council.
"We had someone come back with a picnic and to play. The thing we noticed was how varied the people were. I played a 75-year-old guy ... we had kids as young as 4."
The Western Park events attracted about 70 people each Saturday afternoon. "There is the ball versus wind factor, but that's just part of the challenge," Marieke says.
Emily, who works in council planning, says passers-by stopped, watched, took part and met new people.
"We had parents stopping with their kids, strangers who were playing just started talking to each other. Suddenly the whole space was being used. It became more about the people, it didn't matter what the game was. We have amazing parks in Auckland and we don't make enough use of them."
They've found one public concrete table in Auckland - in the secluded green space behind Mt Albert's War Memorial Hall and keenly demonstrate their passion to The Aucklander. That table was set up under a 2008 Community Board initiative.
The trio has researched how Melbourne-based groups got permanent equipment into a city park and plans to ask Auckland's local boards to play the game, too.
