Wanganui looked nervy, and even a seasoned fullback such as Ace Malo grassed two easy balls. But halfback Lindsay Horrocks scored a vital try not long before the break, darting over after his pack had flooded the ruck with numbers.
North Otago might have felt they could camp deep in Wanganui territory. It was not to be.
Instead, Wanganui's pack, led by the bullocking No 8 Lasa Ulukuta, inspirational skipper and flanker Peter Rowe, and lock Sonny Woodmass, rolled their sleeves up and commanded most of the ball.
That led to second-five Rhema Sagote spearing over for his seventh try of 2014 from a one-two cut move. Then they hung tough, despite a late North Otago try to wing Matthew Vocea, still at St Kevin's College, off a Tenina Sauileoge break.
Ulukuta cracked the champagne and Wanganui drank deeply from the Lochore Cup.
Wanganui have won three Meads Cups and while that is always their primary goal, they will be satisfied to have closed this one out after two trying seasons.
Wanganui (Lindsay Horrocks, Rhema Sagote tries; Ace Malo 2 con) North Otago (Ben Palmer, Matthew Vocea tries; Palmer con) HT: 7-7
