My little girl is 7 weeks old and has a hamangioma on her left eyelid. She was started on propranolol 1week ago and we have already noticed a huge difference. This was prescribed by her pediatrician and we are currently waiting for an appointment at the Royal Brisbane Hospital as they gave a clinic there specializing in hamangiomas. Behaps you could try getting in contact with them if you are still having issues finding a specialist in NZ. Good luck.
