Air pollution levels have increased in several New Zealand cities this year. Blenheim clocked up a record number of dangerous pollution days this winter. The Marlborough District Council began keeping a log of air pollution in Blenheim in 2006 and since then had struggled to keep to the lawful standard of one breach a year. CHLOE RANFORD/LDR Marlborough District Council environmental scientist Sarah Brand says Blenheim did not breach air quality standards over lockdown. Air pollution levels also improved under last year's lockdown.
