There's nothing like a bit of competition to get the juices flowing before a day-long retreat, so when the Pacific leaders were given mahogany saplings to plant, Prime Minister John Key appeared to think it was a race similar to those on the television show Survivor.
All of the 15 leaders were lined up with their saplings, and with coconut shells to scoop the sand around their trees before watering them.
Key got his sapling planted in very quick order before declaring he had won immunity and asking who wanted to be voted off the Tribe.
He later said gardening was not his forte and he was not allowed in the garden by his wife, Bronagh.
However, he appeared happy with his efforts and expected his tree to grow tall and strong.
