The chambers could be over-loaded if both anti and pro-Hundertwasser Arts Centre camps turn up to hear the Whangarei District Council's critical decision about the controversial proposal.
But the public gallery at tomorrow morning's meeting is likely to be swollen further by another group of residents who say the council should be spending ratepayers' money on ensuring the district is a healthy place to live.
It's not an issue likely to raise as many cheers, tears or fears as the Hundertwasser decision, but the Pipiwai Titoki Road Action Group hopes other supporters and rural residents whose homes and businesses are jeopardised by dust pollution will make their presence felt.
Ms Wright said the group, which held a protest road block at Pipiwai in April, will be carrying out a more disruptive road block if HAC gets the green light.
"Rural residents are being treated like second-class citizens although they pay taxes and rates," spokeswoman Alex Wright said.
