Yes, I agree.
The children of anyone with a work visa are entitled to have student visas matching the parent's for length of time, so they can go to school on the same terms as NZ nationals and residents. The spouse can have a partner-sponsored temporary work visa, likewise for the same length of time. (That is an open work visa allowing him/her to work at anything, or nothing, or start a business.) With a work visa of 24 months or more, or as soon as a second work visa gives permission to stay 24 months at least, a person is entitled to use the NZ health service on the same terms as NZ citizens or residents.
