The New Zealand spider with the largest leg span is the Nelson cave spider (Spelungula cavernicola), with a leg span of up to {{convert|13|cm|in}} and a {{convert|3|cm|in}} body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites.[3] The flat huntsman spider (Delena cancerides), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.[4] The huntsman spiders, which are considered harmless to humans, have been collected for use in at least two films. Very few New Zealand spiders have bites that can cause significant injury to humans, and of these, only one – the katipo – is endemic. Katipo bites have been known to cause systemic effects, such as hypertension, seizure, or coma, though no deaths as a result of katipo bites have been recorded for over 200 years. Its more dangerous close relative, the venomous Australian redback spider, has established a foothold in some parts of New Zealand, notably in Taranaki and Central Otago.[5] Fishing spidersThere are four spiders in the genus Dolomedes (the fishing spiders), species which have adapted to hunt on the surface of water. Three of the fishing spiders are widespread on the two main islands of New Zealand. Dolomedes aquaticus grows up to {{Convert|7|cm|in}} across and specialises in open, unforested riverbanks, and lives under rocks within {{Convert|5|m|ft}} of the river. Another species of similar size, Dolomedes dondalei, specialises in forested riverbanks and is also widespread on the mainland. The third and most common species, Dolomedes minor, is not restricted to rivers. Known as the nursery web spider, it makes white nursery webs on shrubs, but is still capable of fishing behaviour. The largest of the New Zealand fishing spiders is Dolomedes schauinslandi and occurs on South East and Mangere islands in the Chatham Islands.[6] SpeciesSpider species in New Zealand include:
