The two teams play at Wellington's stadium in the second leg of the qualifier with the hope of making the World Cup finals - New Zealand for the first time in 27 years and Bahrain for the first time ever.
Having held on for a 0-0 draw when the teams met in the first leg of the qualifier in Manama last month, New Zealand now need a win to progress to the finals.
Under the away goals rule, Bahrain would go through if there was a score draw, and another 0-0 deadlock would mean extra time with a penalty shootout if no goals were scored.
The situation is nothing new for Bahrain.
In their tie against Saudi Arabia to decide who would meet New Zealand, they were also held 0-0 at home, but grabbed a thrilling 2-2 result in Riyadh with a stoppage-time goal.
Macala said the team's experience against Saudi Arabia stood them in good stead for tomorrow's crucial game.
The team also had valuable experience from their 2006 World Cup campaign, when a devastating loss to Trinidad and Tobago cut them out of the finals.
"We have some players that remember this game and of course they are sad and disappointed," he said.
However, he said the players could take the loss and learn from it.
"I think it'll be a very tough game, a good game," he said.
"Because (New Zealand) played in 1982 in Spain, I hope that (they) give us a chance to play our game in the finals." The Bahrain team were feeling the pressure of the match, Macala said, but also emphasised that that type of pressure was nothing they had not experienced before.
"Pressure comes with every game. We were under pressure from 2007 when we went up against Malaysia. Then against Japan, against Oman, against Qatar - every game every point was very important."
Much had been made by New Zealand about how much more experience his team had had in the lead-up to the match, he said.
"We are experienced, but we also have troubles. Do you know how many players have had injuries in the 20 rounds? It is not easy," he said.
Macala said he felt his team were in a position to win the game, but would have to see how the match played out.
"In the first leg I think we were the better team, but here, perhaps the situation will be different."
