Auckland Grammar’s Sam Ulufonua collected the senior boys throwing double with 59.15m in the discus and 17.89m in the shot put at the New Zealand Secondary Schools Track and Field Championships. The 18-year-old says that he tried to get the best with each throw and go with the flow. ‘‘Just got to do it on the day. I’m just backing it up from training and believing in myself that I can do it. It is a good way to finish my last year at school,’’ he says.
