After a successful business career in New Zealand, which made him one of that country's wealthiest individuals, he relocated to London in 1999.

He retains strong links to New Zealand through his development of Gibbs Farm, one of the world's leading sculpture parks.

He is the founder of Gibbs Amphibians, based in Detroit, Michigan, Nuneaton, UK, and Auckland, New Zealand, which pioneers high-speed amphibious vehicle technologies.

[2] Gibbs is one of New Zealand's leading art collectors, and since 1991 has been establishing a sprawling 1,000 acres (4.0 km2) sculpture park at Gibbs Farm,[3][4] which is located on Kaipara Harbour on New Zealand's North Island, 50 kilometres (31 mi) north of Auckland in the Rodney district.

Among the art works installed on The Farm are monumental pieces by contemporary artists including Daniel Buren, Neil Dawson, Marijke de Goey, Andy Goldsworthy, Anish Kapoor, George Rickey, Richard Serra and Bernar Venet.
