Residents Demand Action as Odour Pollution Harms Health in Christchurch

Residents in Christchurch’s Bromley suburb are calling for urgent action following a study highlighting the health impacts of environmental odour pollution. According to the latest briefing from the Public Health Communication Centre, odour pollution can lead to serious health issues, and current regulations are insufficient to safeguard affected communities.

Health Impacts and Community Concerns

The report, titled More than just a bad smell: Odour pollution and health in Aotearoa New Zealand, documented 36 instances of odour pollution across New Zealand, primarily involving meat processing facilities, sewage treatment plants, and landfills. Local resident Carol Anderson, who has lived in Bromley for nearly 30 years, expressed her relief upon seeing the issue gaining recognition. “I’ve seen all along that it was to do with the dust and all the toxic stuff that was in the air. And it was just dismissed,” she said, adding that she now feels “vindicated.”

The report indicates that prolonged exposure to these odours can result in symptoms such as headaches, nausea, and insomnia, mirroring findings from international research. Dr. Jonathan Jarman, the study’s lead researcher, emphasized the need for public health services to advocate for afflicted communities. “Prolonged odours can cause chemical poisoning symptoms,” he stated.

Residents have reported various health issues linked to odour pollution. For Anderson, the situation deteriorated significantly after a fire at the local wastewater treatment plant in 2021 destroyed two filters. She described the smell as “absolutely vile,” making it impossible to enjoy her garden or even hang laundry outside without having to wash it again.

Other residents have also reported suffering from nausea, headaches, and worsening asthma. One local mentioned that during hot summer nights, the stench forced him to sleep in his car at nearby Sumner Beach, rather than endure the unbearable conditions at home.

Regulatory Gaps and Community Advocacy

The Public Health Communication Centre’s report underscores that this problem is not isolated to Bromley but reflects a national crisis, with many communities feeling vulnerable to the effects of prolonged odour pollution. Local councillor Yani Johanson raised concerns about potential changes to the Resource Management Act (RMA), suggesting that the current government’s adjustments may weaken protections for communities against environmental harm.

“Everything we’ve seen coming out of Wellington has been to reduce the protections that go to the community for these types of activities,” Johanson stated. He urged for stronger regulations rather than permissive development policies that overlook environmental and social impacts.

In response to community concerns, Brent Smith, general manager for council infrastructure, acknowledged the negative effects of odour from both the wastewater treatment plant and the organic processing plant. Smith confirmed that the council has yet to receive the latest briefing but is actively working to improve the situation. A new organics processing facility, set to replace the troubled Bromley site, is expected to begin operations in early 2027.

Steps are also underway to address the odour issues at the damaged wastewater treatment plant, with planned upgrades on the horizon. As the community continues to voice its concerns, the hope is that proactive measures will be implemented to safeguard public health and enhance residents’ quality of life.

Health New Zealand has been approached for comments regarding the findings and the ongoing initiatives to address the odour pollution affecting residents.
