Interceptions of high-risk insects in 2023 were lower than the long-run average

We have just updated the surveillance report on high-risk insects caught at our border by New Zealand's mosquito surveillance programme. 

  • Interceptions potentially originating from China, Australia, Singapore and India accounted for over half of all interceptions from 2019–23.
  • There were 10 interceptions of international origin in 2023, compared to an average of 21 per year between 2014–21.
  • Most interceptions from 2019–23 were in Auckland and Christchurch. Before 2019, Auckland had the overwhelming majority of interceptions.
  • Between 2019–23, intercepted high-risk insects were mainly found in household goods and vehicle and machinery parts.
