Kāinga Ora should be operating a not-for-profit electricity retailer for their tenants. Buying electricity on the spot market, and selling it to their tenants at-cost.
In fact, such a not-for-profit retailer could buy and provide electricity to all public entities. This would give them huge leverage to negotiate a low wholesale price. Reducing the operating costs of public services, as well as the household costs of Kāinga Ora tenants.
