"I know this final is the first and there isn't a lot of history around it, but it's the start of something that's pretty big.
"To play in a one-off Test final against India - one of the best teams in the world, if not the best team in the world - to be able to test yourself against the best on the highest and biggest stage, that's what it's about.
"It's extremely exciting, but I don't want to think too far ahead. Don't want to let the occasion get to you, just treat it like another Test match and do the same things you do. It's definitely going to be a special occasion. That's for sure," the Kiwi said.
Wagner battled through the pain of two broken toes in the first Test against Pakistan last December, playing an instrumental role in a memorable win for the home team at Bay Oval in Mount Maunganui.
He needed pain-killing injections during the Test, which the hosts won by 101 runs, after he was struck on the foot while batting on the second day.
"Yeah, it's a tough one. (It was) sort of in the moment and I guess adrenaline and playing for the team -- wearing the black cap is the ultimate drive and it obviously motivates you to go through that.
"It's (also) just everyone else around you encouraging you to do something like that, and trying to bite through as much pain as I could to try and deliver a job. Luckily it came off," Wagner, who is a bit scared of needles, said.
If his heroics at Bay Oval was any evidence, Wagner has a penchant to deliver in trying conditions, and he said he prides himself in playing a role when the going gets tough.
"Test cricket is tough and it's never easy playing in different parts of the world, where it can be challenging.
"You get to test your skills and ability against the best players in the toughest situations. That's where you want to stand up and make some sort of impact, and I pride myself in playing a role when things are tough. I want to put my hand up and have the ball in my hand," he said.
