The Cook Islands organising committee for the Pacific Mini Games is looking at deepening part of Rarotonga's picturesque Muri Lagoon so the outrigger canoeing events can be held there.
The Games CEO, Mac Mokoroa, says the country's vaka groups have approached them about the obstructions posed by coral on the planned course.
Mr Mokoroa says the Marine Department and Environmental Services have been considering options.
"Now the very first one is that they can replant these corals in areas where it will not be a hindrance to the canoe races, or alternatively they can change the course, the whole line of the course, where the corals will not be in the way. Or the third option is that they can hold the racing during high tide."
Mr Mokoroa says any decision on removing the coral would depend on the reaction of the Environment Council and local chiefs.
