Representating Taranaki, Whanganui-born Robertson said he was just as unlucky to lose the first frame in the final as Chand was to lose the second.
"I got the last two frames pretty comfortable. My superior experience proved the difference," Robertson said.
He had a break of 81 during the first two days of the tournament and this was bettered by Hawke's Bay's national champion Bayden Jackson who had a 98 during his semifinal loss to Chand yesterday. Chand recovered from a two-frame deficit to beat Jackson 3-2.
Ironically, Chand finished second in his last North Island final at the Havelock North Club in 2015 when he was beaten 3-0 by Jackson. Robertson beat Capital City's Mark Hannah 3-0 in their semifinal.
Wednesday's plate final saw Taranaki's Denin Bunn, a son of successful national coach Stan Bunn, beat Auckland's Paul van der Straten 2-1.
Robertson also won the AG Challenge Championship tournament at the Wanganui East Club for the seond time earlier this year. Robertson won the Ag Challenge tournament in 2016 when representing Waikato.
A feature of Wednesday's tournament was the fact all members of the New Zealand under-21 and under-18 teams for next month's world championships in Jinan, China, including Chand and Bunn, turned out. Manager of the teams, Hawke's Bay's Dave Judd, was thrilled with how the youngsters performed in a quality field.
"They all performed really well and it was part of a good development process for them.
They all have almost a month to practice what they got beat up on before heading to China."
