How we helped
We developed an economic model and quantified the material benefits of the flood control scheme. We assessed the economic benefits and identified the cost of an alternative scheme. We determined that Otago residents paid 27 percent of the total costs and gained 24 percent of the benefits of the scheme. Canterbury residents paid 33 percent of the costs and gained 76 percent of the benefits. The remaining 40 percent was paid by Meridian Energy, that operates the Waitaki dam further upriver. Our analysis showed that Otago residents were contributing a disproportionate amount to the scheme’s costs.
