It was an emotional time on Celebrity Treasure Island during last night's episode.

Laura, Sam and Toni caught up with Olympian Barbara Kendall who left the island after losing to Shannon Ryan in the elimination challenge.

She set the record straight with former Celebrity Treasure Island co-star Sam Wallace on why they butted heads on the island, her game tactics and why team Mako didn't trade their clues to get some food.

Celebrity Treasure Island continues Sunday 7pm on TVNZ.
