"Water is the lifeblood of the Heretaunga Plains and in many ways it has been taken for granted. As the most important natural resource it needs to be looked after," the statement said.
Mr Yule reiterated yesterday that the event would be an opportunity to inform the public as well as allow people to have their say and ask questions about the complex water issues on the Heretaunga Plains.
"It's about public engagement - while water has been treated as a commodity in the past, people now have a far greater interest in its importance to life in general," he said.
The symposium would cover the current water situation and the science around water among other issues.
He said the final details about who would pay for the event had not been sorted out yet, but estimated it would not cost much more than $10,000 to host, with most costs related to venue hire and catering.
Draft annual plan submissions
The new timing for the inquiry findings meant consultation on the Hastings District Council's draft annual plan and response to the water crisis, including plans to spend $12 million on possible additional treatment, potential new water sources and network enhancements, would also be extended.
Mr Yule said the deadline for submissions on the rest of the consultation items in the draft annual plan would remain the same, closing on May 8, but submissions on the water section of the plan would close on May 18 to give people time to consider the inquiry's report.
