Temperature (wine) storage in Tahiti/Moorea

Hi,

My husband & I are in NZ now, accumulating wine, and we're stopping in Tahiti x 6 days on the way back to the US. It just occurred to us we will need to protect this wine from the 80+ degree temperatures of the islands, ideally around 55-65 degrees (11-15C).

Does anyone have any experience or ideas? Does the airport have storage, do you know if it's air-conditioned?

Thanks!
