The floodgates looked as if they could open when halfback Zac Donaldson scored Hawke's Bay's sixth try a minute into the second half, only for the Bush to fight back with a second try to Olson, who finished off a regulation backline move in the corner.
However it was teammate Andy Humberstone who scored the try of the match. The second-five stayed on the touchline when a penalty was awarded. Priest caught the Hawke's Bay defence asleep with a pinpoint kick that was taken by Humberstone, who beat one tackle to score the home side's final try.
Jarvy Aoake, Junior Waqa and George McPherson wrapped up the scoring with further tries for the visitors.
Despite the scoreline there some encouraging signs from Wairarapa-Bush.
Priest directed play well at first-five and made some telling breaks, especially in the first half.
Olson and the other winger Jimmy Boyle both had busy games, as did loose forwards Liam Devine, Sam Gammie and James Goodger, who was particularly impressive in disrupting Hawke's Bay's lineout ball.
The tight five toiled hard but were always under pressure at scrum time against their considerably bigger opponents.
The forwards were also guilty of poor discipline at the breakdown, giving away seven penalties there in the first half alone.
The backline defence stood up well to early pressure but began to lose shape with the wealth of possession enjoyed by Hawke's Bay.
All in all there's plenty for both coaches to ponder.
