How to tell the authenticity of a New Zealand work visa

The work visa is not authentic. That's from Immigration New Zealand.

I guess what you want to ask is the authenticity of New Zealand OFFER?

If the New Zealand Immigration Bureau has given you a visa, then the job opportunity must be real or fake. There is no way to check this! The only way is to go to the New Zealand government company registration website to find out if this company is real: panies. If the company is no longer registered on this website, it must be fake.
