This is the community's space," Mr Waugh said.
Charlotte Melser, who would run the cafe, said the event started at 3pm and featured free food as well as entertainment from local bands and musicians.
"We're doing it to show the community, to see what we've created but more importantly the movement forward that Castlecliff is taking as a community. It's about celebrating where we're going as a community and where it has come from," Ms Melser said.
And she said they were hoping someone could shed some light on an old glass found when builder Tom Francis was renovating for the cafe.
"It was put behind some wall linings 50 years ago when this original place was built.
There's a rumour the glass may been from the hotel which stood on this site 100 years ago.
"It's very hard to find information on the history of this site, but someone who's still around may know about the glass being put there 50 years ago," she said.
Those contributing to Saturday's event include Jason and Carmel Malcom (Cliff Life Church), Tahi Nepia and Anna Te Rei (Te Kaihau O Kupe Castlecliff Waka Ama), Phil Holden (Matai St community gardens), Des Warahi (Castlecliff Trust board), Graham and Lyn Pearson (Run Coast Care and Progress Castlecliff), district councillor Jenny Duncan and local artist and potter Ivan Vostinar.
