Shelly Bay is a bay on the Miramar Peninsula of Wellington, New Zealand. The area was settled by a collection of peoples from multiple Māori iwi in the 1820s and 1830s. It was later bought by the New Zealand Company, in a sale the Crown apologised for in 2008, admitting that the deed was flawed and promises were never kept. Most of the land was owned by the New Zealand Defence Force for 124 years until 2009. During that time it was used as a submarine mining base, a naval station, and an airforce base, and land was reclaimed.
