A win to Wairarapa-Bush on Saturday would very probably guarantee them a place in the semifinals of the Heartland championship's premier section, the Meads Cup, for the first time since 2006 when they won the trophy.
Conversely, however, a loss would almost certainly leave them needing to beat Horowhenua-Kapiti in the last of their preliminary round games on October 13 to make it into the top four.
North Otago will miss the Meads Cup semifinals for only the second time in the past six years should they lose to Wairarapa-Bush this weekend.
With three wins from six matches, they are sixth on 15 points, six points behind the three teams in third equal, South Canterbury, East Coast and Buller, and seven in arrears of joint pacesetters Wanganui and Wairarapa-Bush.
That suggests North Otago will have to pick up the maximum five points against Wairarapa-Bush and Thames Valley the following weekend in their last two preliminary round matches to have any chance of reaching the semifinals.
Which suggests in turn they will have no option but to play an expansive style of rugby in Masterton because of the need to win and secure a bonus point for scoring four or more tries.
The full North Otago record in 2012 Heartland games is: beat King Country 31-30, beat Buller 22-15, lost to Mid-Canterbury 3-7, lost to South Canterbury 37-52, beat Poverty Bay 24-23, lost to Wanganui 22-39.
