King Country coach Kurt McQuilkin said his team still had plenty of improvement in them but he was pleased with the pressure they kept on Wairarapa-Bush, pressure which often led to penalties which just as often Cunningham converted into points.
The high penalty count against them meant Wairarapa-Bush struggled to get any continuity into their game.
Their backs did look dangerous when given the chance to attack but that happened all too seldom for the visitors.
Inia Katia scored their try and Ben Aoina kicked two penalties and a conversion.
Wairarapa-Bush will confront Meads Cup defending champions Mid-Canterbury at Memorial Park in Masterton next Saturday and they will start rank underdogs there after Mid-Canterbury started their 2014 programme with a 52-27 win over West Coast, and gave every impression of being as powerful this season as they were last.
Poverty Bay, beaten 71-0 by Wairarapa-Bush a fortnight previously and by more than 50 points by Hawkes Bay development the following week, bounced back from those defeats with an impressive 52-12 walloping of East Coast. Poverty Bay, which now has former All Black Rico Gear as assistant coach, ran in seven tries.
Horowhenua-Kapiti came back from trailing 14-6 at halftime to draw 19-19 with Thames Valley and two of the usual big guns in the Heartland championship, Wanganui and North Otago, both suffered defeats, Wanganui going down 31-18 to South Canterbury and North Otago losing 17-9 to Buller.
Championship points:
South Canterbury 5, Poverty Bay 5, Mid Canterbury 5, King Country 4, Buller 4, Thames Valley 2, Horowhenua-Kapiti 2, West Coast 0, Wanganui 0, Wairarapa-Bush 0, North Otago 0, East Coast 0.
