New Zealand is now home to the noble false widow spider (Steatoda nobilis), one of the world's most invasive spider species. First confirmed in Porirua in November 2024, it has rapidly spread across the country, with sightings in Northland, Waikato, Wellington, Nelson, and Christchurch. While not as dangerous as its infamous cousin, the black widow, its bite can still cause painful symptoms and potential health risks.
