It is a collaboration between Pereri King, actor, Puti Lancaster, director, Marama Beamish, designer and Janis Cheng, lighting designer. They also engaged local researcher Moana Munro to depict the history below the Heretaunga Plains.
"We want to connect people with who they are, understand the context of the place, the influences of the past and the challenges they present," Ms Beamish said.
Festival Co-ordinator Pitsch Leiser said the production showcased a local story that was something you could not just buy off the shelf.
"They offer a unique and different perspective through their work which I find very exciting," Mr Leiser said.
The group worked with the idea that water is an essential element to both the physical and spiritual self.
"Water does not need us but we need it to survive everyday, I mean we are made up of 70 per cent water," Ms Beamish said.
Mr King said he used the Bill T. Jones system to devise his role.
"I help give cues to the audience and then look at what the audience needs to come closer and connect with the story."
He said he would use a collection of storytelling techniques and described his acting as a conversation.
"We are both playing. I want them to engage with me so they take away the true experience with them."
The production is going to be performed in three different venues - Parlour Project, The Famous Spiegeltent and Hastings Community Arts Centre, all in locations where the river once flowed.
"I am excited to perform our opening at the Parlour Project, as the river flowed directly below the carpark. It will make our story come to life," Ms Lancaster said.
"We will be able to get a certain level of intimacy that you would not usually get, the feel and approach will shift with each show," Mr King said. The group invited people to come and experience the "buzzy" and "cool" production that would bring you closer to your heritage.
"It opens you up to a whole new perspective of what was once in our backyard and even if you cannot see it now it still trickles below the surface," Ms Lancaster said.
