Medical trials depend on people being prepared to try new drugs or to take part in experimental procedures which may not help them now, but might help others in the future.
There are many reason not to answer calls for help from researchers but without people willing to sign up for trials, better medication and other treatments with real potential to help out a raft of health issues can't get over a crucial hurdle.
Dr Rinki Murphy from the University of Auckland is a specialist in diabetics who often puts out requests for volunteers to help in her research projects.
Lynn Freeman also spoke to Rinki’s colleague Brendan, who is diabetic and signed up for a genetic test.
