Vettori, who had previously indicated that he would stand down as New Zealand captain in all forms of the game following the World Cup, a decision he reaffirmed today, will remain as a test player but said he had not yet decided whether today's match would be his final one-day international.
With New Zealand not scheduled to play again until they tour Zimbabwe in October, he said he would take time to consider his 50-over future.
"I've played my last Twenty20 match ... (but) it's about six months to the next one-dayer so I have a lot of time to sit down and think about it and talk to my family," he told reporters in Sri Lanka.
"Tests are a big part of why I play the game, for team and myself, because there is no better feeling than winning a test."
Vettori relinquishes the one-day captaincy with a winning record, having had 41 victories and 33 defeats from 82 matches in charge.
However, the record drops to 26 wins and 28 losses when results against Bangladesh, who have only become genuinely competitive in the past year, and associate International Cricket Council nations are disregarded.
He had a six-win, 16-loss, 10-draw record from 32 tests as captain and 13 wins and 13 losses from 28 Twenty20 matches in charge.
Vice-captain Ross Taylor is the leading candidate to take over as captain, although Brendon McCullum has also publicly indicated his desire to lead the team.
New Zealand scored 217 all out batting first against Sri Lanka, a score the home team surpassed with five wickets and 14 balls in hand.
The visitors were railroaded by a batting collapse late in their innings, losing their final six wickets for 25 runs after the top-order had set the platform for what would have been a highly competitive total of about 250. It was New Zealand's sixth semifinal exit at World Cups.
