This certainty has been useful but more is needed to ensure that the immigration system can react in a timely and nimble fashion. It is the Government's view that new powers are needed for a time-limited period. Under existing settings, temporary migrants who wish to remain in New Zealand must submit individual applications for a new visa or to vary their existing visa's conditions when the migrant's circumstances change. This can be where they need to be redeployed by their employer into a different role or to a different region, or to look for another job after being made redundant.
