Hello
I used to Live in Auckland.
I climbed Quite a bit in the North.
Kawakawa bay is a new location.
Whanganui bay " the bay" has good climbing in a Maori Communty down a long private road( small access fee)
Waipapa dam is Good.
Froggatt, smiths, Baileys etvc aree OK, Very developed sport.
Bryces climbers lodge, cafe and gear shop is a good pplace to Visit. Bryce has Climbed all over the area for decades so can tell you anything you want to know. He is lovely But gruff.
I used More finger sizes But had up to Cam 4. I don't Know of any one that had pitons etc up there. Most people will be sport climbers only.
There is climbing in the Karangahape Gorge. Never been but it sounds adventurous.
Take a Longer trip to Taranaki- Looks amazing( tradlines)
Search for freeclimb, online guides. I have an OLD 1991 Central north island rock guide which My Mother sent me another second hand copy so Could Send you when you arrive if you pay courier
Most places will Be 2-3hours drive
Tauranga has some keen climbers and a Gym called the rockhouse.
