Pain management specialist reccommendation (private)

I'm on the waiting list to see pain management in wellington under the public health system but the wait is ages and I'm rapidly losing my ability to work (and will to live)

Can anyone reccommend a private pain management specialist without a months long waiting list? I can travel. I'm looking for pain management options other than gabapentin/pregablin, opiates, and antidepressants, because the side effects have been awful but now my GP is out of options
