Meet The Team


  • Dr Daniel Asquith

    I was an archaeologist before I decided to go into medicine. I trained in the UK at the University of Newcastle upon Tyne and qualified in 1997 having also carried out postgraduate research in immunology.

    I spent five years working in hospital and emergency medicine and qualified as a general practitioner in 2005 in Taunton, Somerset. At that point, I first came to Whitianga on a working holiday. My family and I liked it so much, we returned in 2007 and have been here since.

    I became a partner in the practice in 2011. My areas of interest include emergency medicine, paediatrics, general medicine and skin cancer surgery.

  • Dr Hannah Walker

    I joined the team in December 2011. I grew up in Essex, United Kingdom and studied zoology and medicine at the University of Bristol.

    While in Tonga I met my husband, a Whitianga local. I moved to New Zealand to work in Middlemore Hospital and then to the Gold Coast to work in emergency medicine. I returned to New Zealand to complete general practice training which has led me to Whitianga where I now live with my husband, beautiful girls and 2 dogs!

    I became a partner in 2019 and am really looking forward to steering the ship! I am very motivated to improve women's, children's and adolescent health. I also enjoy the emergency medicine Whitianga chooses to throw at us.
