A couple of ladies in my coffee group are with Lesly Hinson & Suki (not sure of surname) based in Howick, and they rave about them - they are apparently open to whatever type of birth you want, and provide accupuncture etc to help you along the way - I wish I had gone with either of them myself! Also heard they are great afterwards, and will exceed the number of govt funded post-natal visits if reqd - eg problems with breastfeeding.
Good luck with you research & decision :-)
