Contaminated debris at Pigeon Bay
Incident date: Early April 2026
Last updated: 1.30pm, 18 May 2026
Christchurch City Council contractors have removed asbestos‑containing material (ACM) that was identified on Pigeon Bay beach. Removal work was completed on 11 May 2026.
Initial investigations indicate the material is likely from a historic, land‑based landfill that has become exposed over time due to coastal erosion. Because of this, it is possible that additional material could be exposed or deposited on the beach in the future.
We’re asking people to remain vigilant and take care when visiting the area.
- Avoid touching or disturbing old or broken building materials (such as sheeting, pipes or roofing fragments) that may be present on the beach
- Take extra care at low tide, when material may be exposed
- Follow any on‑site signage and advice
If you have concerns or notice debris in the area, please contact our Advisory Team on 0800 324 636.
