Off the field Richie devotes much of his time to helping other Kiwis. He has fundraised for the Christchurch rebuild and Leukaemia and Blood Cancer New Zealand. As patron of the Catwalk Spinal Cord Injury Trust, McCaw helped raise $200,000 for research into the development of a cure for spinal cord injury.
In 2009, McCaw and fellow All Blacks Dan Carter and Ali Williams set up the For Everyone Charity. Now called iSPORT, it works with schools, and local, regional and national sporting bodies to support young sportspeople and teams to succeed in their chosen fields. It provides a platform for individuals and community sports groups to raise money for essential items such as kit, uniforms, boots, equipment and travel. iSPORT has also recently partnered with Paralympics New Zealand to help young disabled Kiwis excel in sport.
