New Zealand all-rounder Jacob Oram said on Thursday that a broken finger on his left hand would not stop him playing a full part in the World Cup which starts in the Caribbean next week.

The 28-year-old all-rounder broke his finger towards the end of last month and joked that he would have it amputated if it looked like stopping him playing in the tournament.

He proved in Tuesday's warm-up defeat by Bangladesh that it had not limited his effectiveness as he top-scored for the Black Caps with 88.

"Once I started getting the confidence in my hands again I was all go," he told reporters on Thursday.

"But what I did learn is if I actually try to catch the ball and stop the ball properly, my finger's nowhere near it anyway.

"So it's just trying to get that technique right."

He said the one area of concern that remains is picking up ground balls but that too is getting easier to do without affecting his injury.

Oram also spoke out over the furore caused by his flippant comment that he would cut his finger off rather than give up his World Cup opportunity.

He said he now regrets making the joke which was reported as a serious comment in media across the world.

"There's probably no need to make light of injuries, especially the amount I've had," he said.

"In hindsight the coverage that that comment got was a little bit silly I thought so I regret saying that."

He said the comment was taken out of context. "I thought I had a smile wide enough to show that I was kidding anyway."

New Zealand play Sri Lanka at the 3Ws Oval in a warm-up match in Barbados on Friday and Oram expects to be battling in a similar position in the mid to lower order.

They start their campaign proper on March 16 against England in St Lucia before playing fellow Group C opponents, Kenya (March 20) and Canada (March 22).
