However, if the Magpies first half was described as dull and passive, their second half was explosive and inventive.
Their backline suddenly came to life, putting the Turbos under pressure in the final third and winning a number of key penalties.
Ihaia West kept knocking them over to draw the scoreboard back before the Magpies scored their first try through Mark Abbott.
His forwards helped him on a storming run which resulted in key try just metres from the sticks.
Moments later, a smart read by Robbie Fruean on defence led to an intercept try that helped push the scoreboard out to 27-16.
Manawatu managed to pull one back but West delivered the killing blow with a late penalty.
The Turbos will be hurting, not only because they dominated the first half with no missed tackles and very few penalties, but because they missed a chance to sit third on the Mitre 10 Cup Championship table ahead of their last two games.
Hawke's Bay 30 (M. Abbott, R. Fruean tries; I. West 1 con, 6 pens)
Manawatu 21 (T. Taylor 2, T. Cadwallader tries; O. Black 2 pens)
HT: 3-11
