The second half was a more one-sided affair with Hawke's Bay adding six tries to the two they had scored in the opening 40 minutes, and exposing deficiencies in a tiring Wairarapa-Bush defence.
The standouts for Wairarapa-Bush up front were No8 Johnie McFadzean, flanker James Goodger and prop Kurt Simmonds, while the inside combination of Whittaker and Tim Priest were the pick of the backs.
Former All Black Zac Guildford scored two tries for Hawke's Bay with others to Jarmy Akoe, Shannon Chase, Billy Ropiha, Tyrone Elkington-McDonald, Brendan O'Connor and Jonah Lowe. Elkington-McDonald also kicked five conversions and two penalties and Ihaia West kicked one conversion.
