"Heaps of things have come together that have made for a successful season, so far. But then we've still got a job to do on Sunday."
The Turbos were rated as $25 outsiders to win the championship when the season began, but Rennie said they had built something special during the past few years by working on developing their homegrown talent.
"We've got a lot of guys who have had offers to go to other places but obviously this group has stayed and that's made a difference," Rennie said. "So it's great that a lot of those guys who grew up in the Manawatu are now involved in the re-emergence of footy in our area."
Previously, injuries and a lack of depth have struck like the plague, but Rennie has had the luxury of picking a regular starting XV this season, in between rotating his hard-working loose forwards.
One other factor, which has certainly helped the Turbos' cause, is the form of first five- eighths Aaron Cruden.
After being injured during a stretch of the Super Rugby campaign, benched by the Hurricanes and dropped from the All Blacks late last year, Cruden has spent plenty of time watching from the sidelines during the past 18 months, rather than do what he does best out on the paddock. He has put the disappointment of missing out on a World Cup spot behind him to guide his side to the final.
"I'm really happy to be getting consistent football week-in, week-out and it's with a really good bunch of boys," he said.
"The team's bonded together really tightly and I think that's showed on the field and it's good to be playing week-in, week-out and just sort of being able to get a bit of momentum into my game."
If Cruden can deliver a performance similar to what he produced two weeks ago against Waikato, when the Turbos toppled the premiership finalists 54-20, Manawatu will rate their chances against Hawke's Bay and the 22-year-old said playing at home was a huge factor.
"It's awesome. I think we've worked really hard this year and it's been rewarded with a home final. It's going to be outstanding, but we know the job's not done and Hawke's Bay are going to throw everything into it, so we need to be on our A-game."
The players have given FMG Stadium a nickname - The Boneyard - after their exploits this season and it's something that's been adopted by both players and fans.
Manawatu won all five of their regular season matches in Palmerston North this year and Rennie said he was a fan of the name.
"We tried to come up with a name, where for visiting teams it's difficult to come. While I can't remember the boys' terminology, it was something about 'where dreams come to die', or something like that."
Hawke's Bay, Northland, North Harbour, Taranaki and Waikato have all had their dreams killed off at The Boneyard during the past few months and Turbos fans will be hoping for one more big Manawatu performance this weekend.
