Dan Te Whenua Walker is a proud husband and dad. His main whakapapa links are to Taranaki, Scotland and Ireland, while being born in Christchurch and now living in Tāmaki Makaurau (Auckland) with his whānau. His son Joshie was diagnosed with bone cancer Ewings Sarcoma in January 2021 at ten years old. It turned his life upside down, however, through the strength of Joshie and the support of his wife Michelle, whānau, friends, community, and many people in the health system – they are on the other side of his treatments and Joshie is doing well.

Dan is a leader in business development and relationship management with an extensive focus in the IT and tech sector. He has a passion for Māori Whānau Ora and initiatives that support iwi, hapū and whānau. Dan is Director of Tātaki Auckland Unlimited, Ringa Hora, Deputy Chair of NZ Māori Tourism, Board Member of RMHC & CCF, Board member of Te Rūnanga o Ngāti Ruanui iwi and a variety of other community and non-profit roles across Aotearoa.

Stephen is a partner at PwC New Zealand leading the firm’s Forensic Services and Leadership Development practices. He is PwC’s Ethics & Business Conduct Lead.

Stephen’s early career was in the New Zealand Police and after qualifying as a detective he moved to the Serious Fraud Office (SFO) as an investigator. After leaving the SFO, Stephen had two senior roles in leadership development, and joined PwC in 2012.

Stephen’s involvement with Sarcoma started with a diagnosis of a soft tissue sarcoma in June 2020 where he became acutely aware of the need for information and is told he wasn’t backward in asking for it. He brings his professional business experience and Sarcoma journey to the Trust, in the hope that awareness and education will improve outcomes and lower anxiety for those who are diagnosed and undergoing treatment.  Previously a daily walker, for exercise, the removal of the sarcoma from his leg challenged that habit, and he is now back to the distance walking he previously enjoyed.
