Residents in Christchurch are expressing frustration over a persistent odour from the Christchurch Wastewater Treatment Plant, with Environment Canterbury receiving over 260 reports since Saturday evening. Staff are actively monitoring conditions and responding to reports.

Community members have criticized the Christchurch City Council for inadequate communication regarding the issue. Health New Zealand has warned that hydrogen sulphide exposure can lead to nausea, headaches, and other ailments, although long-term health effects are deemed unlikely. The City Council acknowledged the unpleasant situation, stating they are working to support recovery and reduce odour levels, but noted that conditions remain largely unchanged, with low dissolved oxygen levels contributing to the ongoing smell.
