For Walter Nasarek, it will be his second time to Bangladesh on medical duties but the sheer scale of providing palliative care to community health field workers in the world's largest refugee settlement isn't lost on him.
The staff member at North Haven Hospice in Whangārei, together with palliative medicine specialist Dr Kees Lodder, flew out on Sunday for two and a half weeks to help other health professionals at the refugee camp in Cox's Bazar, southeast Bangladesh.
The camps are spread over more than 14sq km and house more than 1 million Rohingya refugees displaced from Burma.
Both will volunteer their time training those working for agencies such as Red Cross and Doctors Without Borders, and educate them on palliative care pathways for helping the sick.
Nasarek, originally from Germany, did leprosy work with his wife for seven years in Bangladesh in the 1970s, and said his heart still bled for people in the impoverished country.
