Hello from a round the worlder! Hawaii next!

[egrek]

Hello all, English male joining up to find out where is good to dive where!
Just out of New Zealand and heading to Hawaii, USA (south west) and on to Mexico if all goes well!
Anyone any tips for any of those places?

I've 50 dives now, all from this trip after learning in Cambodia and Vietnam, lots of diving in Thailand and Australia on the reefs. Wondering if I should dive the UK when back home? (Sounds cold)

Thanks!
