You can also try Business Mentor NZ. They have a range of mentors and at a low fee. Alternatively you can also speak to your Regional Business Partner which is a government funded free service. The business advisors will be able to give you some topline advise and give you a few recommendations with regards to the right mentor for you. There is also some funding through them that you may be able to access.
Hope that this helps.
If you need to, feel free to reach out again.
All the best,
