Can I work once I reach 60 years old.

I have a work Permit category B for working in Shenzhen China. Holder of a New Zealand passport. Have been working for the same company 10 years teaching golf as a golf professional.
I am 56 years old. What are the chances of me being able to continue working for this company once I turn 60 years old. Can the company apply for a special extension come closer to that time.
