Former CBA chief lists Darling Point duplex

New Zealand businessman Sir Ralph Norris is selling his luxury Darling Point garden duplex seeing as he's now spending more time in his home country.

The former CBA chief, who earlier this year stepped down as the boss at Fletcher Building, paid $5.15 million in 2006, the same year he was appointed a distinguished companion of the New Zealand Order of Merit.

He bought it from the rag trading Gazal family.

The Darling Point duplex has three bedrooms and three bathrooms.

It has views from Rushcutters Bay to the city skyline.

Every room opens to the wrap-around landscaped alfresco spaces. The entry level with second living area opens to a heated swimming pool.

Ballard Property agents Mark Lowe and Amanda Cook have a June 23 auction.

They describe it as a first-class entertainer.

Norris took the top job at CBA in 2006.
