"And I don't blame the Hundertwasser Foundation for following through on its pledge to withdraw the project from the council."
Meanwhile, Ms Mai has welcomed news of a push by business leaders to get private and Government funding for HAC.
On Thursday, Whangarei businessman and chairman of Whangarei Economic Development Group Barry Trass said a group of business leaders, private individuals and community members were working to get private funding to keep the project alive and had already spoken to the foundation about it.
"We feel this is too important a project to just let go. We are a group of people who have done a lot of work on this and really back the project and we're not just going to sit back and do nothing," Mr Trass said.
Ms Mai said she was disappointed HAC got scrapped by the council - which has spent about $1.6 million on the project so far - but many people had concerns over it being funded by ratepayers.
She said there would naturally be a grieving process for many people involved in promoting HAC, but that would subside.
Vienna-based Hundertwasser Foundation, which allowed the council to proceed with the project, is receptive to private funders taking over the scheme.
