Start up business with my parents

Hi, I am looking to start a business with my parents- food truck. They are Vietnamese citizen and I am a New Zealand citizen. They have money to invest for starting up the business.
Would this allow them secure working visa or any other visas to stay here?
Any help would be appreciated.

Thank you in advance.
