Captain and hooker Ash Dixon and halfback Folau Fakatava were close behind Walker-Leawere. Although Dixon blotted his chances when he thought he scored a try late in the first half but was five metres short.
"I'll have to shout the boys a box of beers for that one," Dixon quipped afterwards.
He admitted his troops came out of the gates too slow and a poor attitude and lack of discipline let the visitors down during the first quarter when the Taniwha dominated.
"I'm still happy to get five points up here where it has been a bit of a graveyard for us. We know we still have a lot of work to do before Friday," Dixon said.
As expected the Northland forward pack was more than competitive. Powerful No 8 Jaycob Matiu and busy Fijian lock Temo Mayanavanua were inspirational.
All Black Sevens representative and Taniwha fullback Scott Gregory made the most of his limited attacking opportunities.
Ozich was happy to report centre Stacy Ili, who earnt his blazer after clocking up 1000 minutes, was the Magpies only injury concern after collecting a charlie to his quad. Lock Michael Allardice, who made his 100th first class appearance, can be proud of his contribution off the subs bench in his first outing of the season for the Magpies.
