Tui, Auckland Council’s first biosecurity dog is sadly no more. For 13 years, a long time in dog years, this Foxy-Jack Russell terrier was part of the conservation dog programme and spent her life sniffing out rodents who threatened our native species. Tui was part of the Million Dollar Mouse project team who in 2018 travelled to the sub-Antarctic Antipodes Islands, a UNESCO World Heritage Site, to confirm the 2016 bait drop had been successful and the island was finally “mouse free”.
