Property owners had been further angered when, following the council's signalling of substantial sewerage rate increases for Hihi, "under the guise of fairer rates'," details of prior expenditure obtained from the council indicated that the rates collected had exceeded capital expenditure by well over 200 per cent.
"Despite this, the council appears to have assigned Hihi a debt burden of $229,468, presumably from works carried out elsewhere," Mr Marsh said.
"As such the council's demands for substantial rate increases deserve an independent review."
The current year's sewerage charge at Hihi is $917, a 37 per cent increase on last year's $669. The district council's current proposal for the 2013/14 year would lift than another 88 per cent, to $1725.
