We use http://www.firstcapital.co.nz/ who are based in Christchurch and more specifically Dai Eveleigh. He managed our pension transfers and currently manages our investment portfolio here in NZ. I was pointed in his direction by word of mouth from the Ex. Pat forums as he often posts advice to members questions.....plus he also did us a good deal.
I have no affiliation with First Capital nor do I gain in recommending their services to others
