Our Board and Team

Joli Wescombe

Chair, Manager

Joli has been on the Management Committee and board of Hamlin Fistula NZ since 2015, serving in communications and fundraising and was appointed Chair in November 2021. She provides management and oversight of strategic and operational matters. With a background in midwifery, Joli brings a passion and knowledge of maternal health in majority nations. She has a PgDip of International Development and is currently pursuing her PhD, studying midwives as agents of change in developing maternity settings.

For several years Marty took teams to Ethiopia to do voluntary building work with Habitat for Humanity, including a joint venture building project with Habitat and Hamlin Fistula at Desta Mender.
