I was there in mid-june this year and stayed on the NW side of Aitutaki.
Many parts of the lagoon have coral reefs just below the surface, so aren't really suitable.
I launched one day from near "samade's on the beach"
around about here:

not the greatest launch spot so assisted it probably the way to go.
Its pretty much always a SE wind.
But i can totally recommend going out to honeymoon island with the guys from south pacific kiteboarding. I emailed them, got a lift in their boat to the island and was out all day for a very modest fee. They dropped me off to my hotel too.
