Napier’s High-Density Plan Sparks Solar-Panel Shadow Dispute

Proposed Six-Storey Housing and Threat to Solar Energy System
Napier City Council’s draft District Plan would permit non-notified six-storey developments on 1,595 properties across the central city and Taradale. One of the targeted sites is a 39-home complex owned by state-housing agency Kainga Ora, situated opposite the Watson family’s residence at 8 Hall Street. The Watsons have installed a fully decoupled residential micro-grid that supplies the home with solar power. They warn that a six-storey building erected as close as 10 m north could cast a “sweeping shadow” that would cripple the system’s output.
Background: Napier District Plan and High-Density Zones
The plan, first introduced in 2023 and amended in 2025, is currently under 12 separate Environment Court appeals. A spokeswoman for the Court said the hearing schedule is uncertain and no decision date has been set. Council officials note that the plan merely outlines where buildings up to six storeys could be built; it does not guarantee development on every listed site.
Financial Impact on Watson Solar Installation
Laura Duncan of Harrison’s Solar Hawke’s Bay calculated that the proposed building would reduce the system’s generation from 46.9 kWh per day to 28.0 kWh per day. Consequently, the Watsons’ annual electricity savings would fall from $5,190 to $2,850, more than doubling the payback period from 12.5 years to 26 years. The Kainga Ora property has a capital value of nearly $9 million, and the agency has indicated it will sell the site without specifying any development requirements.
Official Statements & Responses
“However, once a property is sold, Kainga Ora has no role in, or influence over, how it may be developed in the future,” — North Island Graeme Broderick National MP Katie Nimon told the Watsons her office had raised the issue with relevant agencies and ministers, but added that “While I appreciate the constituent is disappointed, MPs cannot intervene in individual property or planning matters or direct the decisions of government agencies.” — Watson Council spokespeople declined to comment on the hypothetical shading impact, noting that any future development would be assessed against the planning provisions in force at the time.
