Seeking advice - Bouldering/healthcare/bank

Hello all!

Title says it all tbh, I am moving to new Zealand on the 31st August from Australia and am looking for advice on the best bouldering gym memberships to get (which offer the best gyms/locations/services) as I go 3-4 times a week, what's the best healthcare option (I am a British citizen) that you guys have gone with and liked the most and what the different banking options are that you like or offer the best valuation for oversees foreigners as I will be coming over on a whv.

I have done some of my own research but think it's always better to get locals opinions on these things

Thanks in advance!
