Hi Newmamma
No I didn't end up going to RNSH, I decided to go private and went to North Shore Private and I have to say I had a great experience. I didn't want to go home! They really looked after me and our beautiful little baby girl who was born on 3 June. Can't believe it's been 8 months. If private is an option for you then I can definitely recommend NSP but if going public then I'm sure RNSH will be fine. There are a couple of new mums I've met through mother's group that went there and as far as I know, all went well.
Good luck
PS. I don't know of anyone that actually used the birthing centre, they just went to the normal delivery suites.
