Nature and conservation
The internationally-renowned Boulder Bank is a natural spit of boulders, formed of the debris of land slips from the Mackay Bluffs, swept southwards by sea currents over 10,000 years. The bank is 13 km long, the last 8 km forming a spit which separates Tasman Bay/Te Tai-o-Aorere from Nelson Haven. It's width varies from 55 m at high tide to 240 m at low tide.
History and culture
Māori camped on the bank and fished there. They used boulders from the bank - some up to 50 kg - to hammer the rough forms of stone tools from quarries in the nearby hills.
The shelter offered by Boulder Bank was a major factor in choosing the site of Nelson. In 1848 a beacon was erected near the end of the bank and, in 1862, the cast iron lighthouse building that remains today. In 1906 a cut was made in the bank to allow easier passage to Nelson Harbour for shipping. 'The Cut' now separates Haulashore Island from the bank.
