In 2002, Glenn donated $7.5 million to the
University of Auckland for the development of the Business School's premises and facilities and ongoing improvements. This contribution is believed to be the largest private donation in New Zealand educational history, and was driven by Glenn's belief in the business school's mission and in the benefits high quality business education holds for New Zealand business and society. As a result of this gift the business school's complex, opened in early 2008, was named the
Owen G. Glenn Building. Owen Glenn followed his initial $7.5 million donation by, in 2008, donating an additional $500,000 to establish the Barry Spicer and Owen G Glenn PhD Scholarships. These scholarships received matched funding of $250,000. In 2008 Glenn claimed that the New Zealand government was considering making him the country's honorary consul in
Monaco, but such an appointment never eventuated. His political donations to the
New Zealand Labour Party and
New Zealand First, which both the political parties denied receiving, caused some controversy in New Zealand politics at around the same time. On 9 September 2008, Glenn gave evidence to the New Zealand Parliament's Privileges Committee regarding the accuracy of statements made by
Winston Peters, Leader of New Zealand First, about the donations Glenn had given to Peters. Parliament ultimately censured Peters for failing to declare the donations. Glenn supports a number of international charities through the
Glenn Family Foundation and helped establish the
International SeaKeepers Society. The foundation also supported
Hockey NZ, helped it achieve rights to the hosting of the
2011 Champions Trophy, which were taken from
India due to organisation failures. Following the
2011 Christchurch earthquake, Glenn donated $1 million to the
Christchurch earthquake recovery fund on behalf of the Glenn Family Foundation. He stated, "I grew up in New Zealand, it holds a special place in my heart and to see such devastation, such hurt and such loss makes you want to help. This donation is something I can do and I strongly urge other expatriate business people to do the same. We all need to pull together and while we are a small country, it is a country made up of people with huge hearts. That's what gets you through in times like this." == New Zealand Warriors involvement ==
