I was buying from Amazon until I got ripped on an item.you guys got rock auto in NZ ? i guessing so but shipping usually to issue . i find some decent deals on amazon too ….
Rock Auto has been my go-to for the regular parts - their shipping is the fastest and the best value for money....and I have a fridge door covered in their magnets.
Summit is good but they don't know how to pack conservatively - the box is always three times bigger than necessary - much like what Year One does. I'm sure they get a kick-back from the shipping.
For anything specialised I have a few good friends who help me out when parts are available.
