"I think the guys are pretty excited to do what no other NZ side has ever done before -- come over here and win a one-day series. The excitement in the group is very high," the New Zealand pacer said on the eve of the series decider.
India-New Zealand bilateral rivalry dates back to 1988 when the Dilip Vengsarkar-led team made a clean 4-0 sweep against John Wright and Co.
Their worst defeat has been in 2010 when Gautam Gambhir led India to a 5-0 rout against Ross Taylor and Co.
"Everyone is really looking forward to tomorrow. It's been a long tour for some guys and it'll be nice to finish what's been a tough tour on a high note. The spirits are high and everyone is excited about the challenge for tomorrow," Southee added.

"They're all very young and still learning the game and so I think it's exciting in the years to come with those three guys all in their early to mid-20s with big future ahead of them. I don't think it's a worry at all, it's one of their strengths going forward over the next possible 10 years, we'll have three guys fighting out keeping each other on their toes."
"He's a quality player especially when India is chasing, his record chasing is phenomenal. He's obviously a big wicket when any side plays against India. Him and Dhoni they're records are unbelievable.
Southee said it's not just Kohli but the others also pose an equal threat.
"We have to keep taking wickets. They got quality players in and around those two. We saw the games we've won its come down to their last wicket partnerships. They've scrambled few runs as well. Not only Kohli but it's important to keep taking wickets.
