WaiBOP then found the dramatic late winner with Neil striking home after being played into the Canterbury box.
Smith was delighted with his team showing some strong character to earn the points.
"I don't think the heart can take a few more games like that," Smith joked.
"Full credit to the lads, we spoke about what we needed to change at halftime and the lads came out and turned the game around. We've spoken about that recently, the resilience within the group, and that's relevant today in the fact that it was a team performance. It personified the spirit that's in the team for sure.
"I've said constantly we think we're a playoff team. To be a playoff team you've got to win at home, initially. We had a great performance down in Dunedin last week and again we've showed today there is a bit of fight and a bit of battle.
"They're coming to training, they are working extremely hard and it's shown on the Saturday."
