Air Tahiti Nui is pretty easy on checked baggage: one bag 50 lbs free. You'll get a pass on an additional bag if you mention it is scuba
gear, I've never seen them open to check. I did have the counter guys in PPT ask for a C-card on the flight to RAR, (only one was required for four of us).
C&I are really uninterested in checking the LAX flights, just going through the motions.
The more difficult is the PPT to RAR flight, it's on an ATR and has serious limits to baggage, depending on the passerger loads. The local Air Tahiti (not Nui) WILL charge you excess baggage fees
something like 2 €/kg. They do have a higher airfare based on a 50kgs allowance and you can get the Scuba
bag allowance too.

I'd pass on the Bud, it's just not worth the weight premium AND Hinano is really a nice easy drinking beer
. Do bring hard liquor it's more than $60/fifth there for anything!
Provision in Uturoa at the central market and the Champion Supermarket. Fresh fruits and vegs are cheap
and fresh caught Ahi is REALLY cheap
(fisherman by the Uturoa town dock). Expect to pay about 35% more for groceries; basics (rice, flour, potatoes, etc may even be cheaper) Anything imported will be disportionally expensive.
