Shane Reti is not your average doctor.
His interest in medicine has also led him take a holistic look at community health.
He has examined community health issues such as how to improve appointment rates at public hospitals, and once offered to fund a $70,000 survey on fluoride, out of his own pocket.
Now, Dr Reti has found himself involved in the aftermath of a terrorism attack in Boston.
He has been mandated by the New Zealand Embassy in the US to accompany the consul-general around the five Boston hospitals which took injured from the blast site to see if any of them are New Zealanders.
