Bob Askew, the environmental health officer from Nelson whose story also features in A Thousand Hills, describes himself as the least likely model of an aid worker ever - a cross between Frank Spencer from Some Mothers Do Ave Em and Mr Bean.
"One of my colleagues asked how many refugees were in the camps and when I told him around 200,000, he said, 'well, there'll be 200,001 when you get there'!"
Born and raised in Yorkshire, Askew emigrated to New Zealand in the early 1970s and has spent his 40-year career as an environmental health officer specialising in food safety issues. One of his major achievements was developing an award-winning Safe Food Handler programme.
Now a grandfather, he had never travelled to anywhere like Rwanda when, in 1994, he joined the Red Cross because he felt he had to "do something". At one stage in his career, he was responsible for health and safety checks on funeral parlours but was so squeamish he would avoid visiting if he knew there were dead bodies there.
"And then I found myself in this place where 1000 people a day were dying of cholera and there were dead bodies everywhere. I just had to get on with it.
