Very often the leaves will yellow and fall off newly purchased roses, just due to the fact that they've been moved to a new location. If they were greenhouse grown, the direct sun can set them back a bit. If you move them to a bigger pot or the ground, it can be transplant shock.

I've had new mini bushes lose all their leaves a couple of weeks after purchase. Just keep watering them regularly and during the growing season they may put out a whole new set of leaves.

Here is a link to the list of Consulting Rosarians associated with the Rose Society in Honolulu. I bet any of them would love to chat with you about growing conditions on the Islands:
