On her final leg, Smith attacked and led Begg into the final exchange, putting van Bentum in front with one lap to go. The crowd were on their feet as van Bentum held an exhausted Begg at bay into the final bend and scrambled home for a tremendous victory.
Van Bentum, Smith and Daina Gibbs leave for Germany in March to train and race European In-Line Cup events for several months. They will be coached by multi-world champion Kalon Dobbin as part of his Arma Wheels team.
Wanganui's Eden Smith dominated the intermediate men's field to win his first national titles in the 300mTT, 500m and 1000m. It was a fitting reward for Smith who spent the road and track nationals doggedly chasing ice-skating star Zac Biggs, who was overseas for this event.
Andrew Jones faced a class senior field dominated by Christchurch's Ollie Jones but went well, posting the third-fastest NZ 300mTT time and making the 500m final. He and Smith also came third in the men's 3000m relay behind Christchurch and two Czechs.
Drew Brennan had a great national debut in the primary boys' and was unlucky not to win a title. In each of his races with Hamilton's Jackson Fellows, the pair out-distanced the field. Alas, inexperience and some bad luck cost Brennan, but he still bagged four silver medals.
