The draw left the sides in the middle of the Lochore Cup group, while King Country's deadlock with in the away game with Thames Valley has them as the only other unbeaten team heading into the big clash with neighbours Wanganui.
Thames Valley led 8-6 at halftime with both team's scoring two second half tries, with a penalty by King Country's Zayn Tipping letting them tie the home team and stay in the Meads Cup group.
Wairarapa Bush could not quite crack the top four despite a second straight win away from Masterton, upsetting Mid Canterbury 26-16 in Ashburton.
The visitors were added by getting a penalty try which automatically means eight points, while Tim Priest converted both their other tries and added a penalty to create the 10-point buffer.
Big movers on the table were Buller, who made the long trip to Gisborne and came away with a crucial 30-18 win over Poverty Bay - the biggest winning margin of the round - which rocketed them from eighth to third with the prospect of climbing higher with upcoming games against the minnow teams.
Again, returning first-five James Lash was the star, scoring three of their four tries and adding three conversions as Buller got maximum points while Poverty Bay fell back to ninth.
The minnow teams East Coast and West Coast played out the match which could be an early indication of who gets the wooden spoon, and it was West Coast who gave their Greymouth supporters something to smile about with a 36-30 comeback win.
Leaking early tries and still trailing 24-20 at the break, West Coast scored their fifth try to narrowly take the match, with hooker Troy Tauwhare getting a double.
Long Fisiioi scored two tries for the visitors.
