He has resided in Christchurch ever since, where there is now a street named after him Sir Gil Simpson Drive.
Simpson is the founder of the Aoraki Corporation (later known as Jade Software Corporation), developers of the LINC 4GL and Jade programming language, who are also well known for their past sponsorship of Christchurch's Jade Stadium. More recently he founded Jolly Good Software Pty Ltd in 2006.
