A Waitaki district councillor says a proposal to build an indoor stadium in Oamaru would be a "noose around the neck" of the district's ageing ratepayer base.

Cr Jan Wheeler voted against receiving the 154-page Sport Otago indoor stadium feasibility study at the Waitaki District Council's community services committee yesterday.

Wheeler, who is deputy chairwoman of the committee, says the study has "quite a few gaps" and the costs indicated, up to 25 million dollars, are "outrageous".
