The MotoSouth , KTM and Kawasakisponsored annual event was run over three days , from Friday through until Sunday ( April 14-16 ), at The Sandpit track on Pit Road , at Otatara , on the southern outskirts of Invercargill , and , in most cases , it took until the final lap of the final race before a title winner could be declared . The racing at the junior nationals was again this year incredibly fierce , with the elite of New Zealand ’ s junior motocross talent , aged between eight and 16 years , all determined to make their mark . And it was interesting to note that fresh names were to be engraved on all the various class trophies this year . Best of the riders in the eldest age category , the premier 14-16 years ’ 250cc class , was Pukehina rider Flynn Watts , with Levin ’ s Phoenix Van Dusschoten forced to settle for overall runner-up , while Silverdale-based former Invercargill teenager Seth Morrow completed the 250cc podium . Watts finished 2-1-1-2 in the first four of five 250cc races in Invercargill , putting him in a strong position with just one race left to run on Sunday afternoon . “ I knew where I had to finish in my last race , so just relaxed a bit and settled for fourth ,” Watts
