"People are always asking me when? when?" the 36-year-old Lara said on Sunday. "I say to them 'You tell me."
Lara's comments to reporters came at the Carlton Ground outside Bridgetown, where Trinidad and Tobago beat Barbados earlier in the day to win the regional title.
Trinidad won the match by 264 runs for their first regional four-day title since 1985.
The Trinidadian made cricket history in November, breaking the sport's Test-run record with 11,204 runs in 121 matches.
The West Indies team were due to leave for New Zealand on Tuesday, without Lara. He said he had opted out of the One-day matches, but would fly in early next month for the three Tests.
The player said he would take advantage of his holiday to take part in Trinidad's carnival, which lasts through February and is one of the biggest in the world.
"It's part of my country's culture and we all look forward to it every year.
