Fleming is set to beat Arjuna Ranatunga's one-day record

He will set a new record on Wednesday when he leads them for the 194th time in a one-day international.

And the game against Pakistan in Mohali will decide whether the Kiwis reach the semi-finals of the Champions Trophy, a tournament they won in 2000.

But Fleming is already thinking about next year's World Cup and admitted he has a "burning ambition" to win it.

"The biggest worry for us is that we have been inconsistent in big tournaments.

"I think we are a side that gets a bit comfortable once it has won a game," the 33-year-old commented.

That view has been born out at the Champions Trophy with the Kiwis beating South Africa in their opening game and then losing to Sri Lanka after under-performing with the bat.

Fleming has made more than 13,800 runs in Tests and one-dayers and his wicket remains the most prized among opposition bowlers.

He acknowledged that for New Zealand to win the World Cup, he will have to produce the goods with the bat in the Caribbean.

"I just have to do my job, that's getting runs. If I do that, my captaincy is better, my decision-making is better, and the younger players tend to follow that lead," said Fleming.

Another important factor is avoiding injuries to key players, which has not been the case in India where strike bowler Shane Bond and all-rounder Scott Styris have been struggling with niggles.

"Other countries like Australia, India, England, have a number of players they can call on. We don't have that luxury.

"We still hurt when we lose a Shane Bond or Scott Styris because they have varied experience," Fleming added.

"We are trying very hard to keep them on the field, and looking at the World Cup, that's what we need to do.
