I have a solution to both problems. Allow suitable operators to run whale watch/swim trips as they do in Tonga. They are booked out all season, and Rarotonga tourism would be inundated by people who are (like us) besotted with humpbacks. It does the whales no harm and everybody, including the Whale Centre, would make a mint.
We have been coming to Rarotonga every year at this time from the south island of New Zealand, and it would also certainly help visitor numbers if at least one airline could be persuaded to once again run a direct flight from Christchurch to Rarotonga. That, and suggestions above should see visitor numbers booming.
