Deralie graduated from the University of Auckland, School of Medicine in 1998. She works an Obstetrician and Gynaecologist at Te Toka Tumai, Auckland and is Lead Colposcopist at National Women's Health. She has worked as a colposcopist since 2008, initially in Whangārei, then returning to Tāmaki Makaurau in 2010.
Deralie believes cervical screening and having a colposcopy should be an empowering journey. She teaches house officers and registrars about colposcopy and cervical screening; and incorporates a trauma-sensitive approach into her teaching and practice. She is a vocal advocate of HPV self-screening and shared decision-making in cervical screening. She is particularly excited about this next phase of the cervical screening program in Aotearoa. One of her career goals is to see colposcopy become obsolete.
