Horsley is involved with supporting the One Percent Collective run by Pat Shepherd Loren doing voiceovers, casting, and acting in its promotional videos. The One Percent Collective supports small New Zealand charities. Two of these charities, Kaibosh and Amped4life, are described as being close to Horsley's heart. Kaibosh is a Wellington-based charity that collects surplus food from retailers and redistributes it amongst local charities, who then give the food to people in need. Amped4Life works directly with schools, industry and the community to tackle the underlying causes of drug and alcohol abuse.
