Kamo's Scott Tanner cashed in from open play not long after his side had missed a penalty, responding to Central Brown's goal from former North Force coach Bruce Plunkett.
Smith added that while the draw was a fair result, it was disappointing for him as they had planned on leaving the Otaika Domain with three points in the bag to put more pressure on table-topping Kerikeri. He conceded that it only meant more importance would be given to next week's match-up against Kerikeri.
Smith said the conditions had little effect on his side's game plan, saying that if anything the heavy afternoon rain had helped conditions.
"It certainly didn't turn into a mud pit and we were still able to pass and play that [passing] game," said Smith.
Central Brown captain Jake Mabbett said it was no secret his side was physical and keen to defend their dominance at home.
"The guys are pretty proud of that," Mabbett said. "You understand that all things have to come to an end, but I think the guys don't really want [their undefeated run] to.
"We always said if we were fully committed we could get a result against Kamo. [Physical play has] sort of always been a club mentality and the way the club plays, there's a bit of pride and aggression when playing on Saturdays. [And that pride] turns into the Central Brown way."
Mabbett said it was a little disappointing that his side could not cash in on some chances which could have sealed a win.
In a match which included four yellow cards for foul play, Mabbett was not surprised as tackling technique went out the window in the conditions.
"There was some bad tackling, but you're always going to get that in the [wet and slippery] conditions."
