Kirkpatrick was once married to Gilda Kirkpatrick but they divorced last decade.
The family-owned Auckland property investment specialist James Kirkpatrick Group has a wealth estimated at around $800 million.
The company’s website says: “We are an Auckland-based, family-owned and operated, property investment company. We have been involved in Auckland’s property market for 60 years and have been through many cycles of the property industry.”
The business has commercial and industrial properties for lease, including warehousing, office warehouse units, office buildings, showrooms, retail and yard space.
The Herald reported in June how the business was planning an 11-level $100m mass timber office block for a prominent Karangahape Rd site.
James Kirkpatrick Jnr, group chief executive and managing director, said at the time the building was planned to rise 10 levels from the Karangahape Rd elevation and have around 9500sq m of office space.
In the obituary, Kirkpatrick’s family said in lieu of flowers or gifts, they invited donations to the Kindness Collective, a charity supporting children and families in need across New Zealand.
