The Government is cracking down on serious immigration breaches. It's announced it will strengthen deportation settings on the same day that Immigration New Zealand revealed there are more than 20,000 people who have overstayed their visa. Immigration Minister Erica Stanford says there are gaps in the current system. For example, under the current rules, someone who commits a serious crime can't be liable for deportation if they've held a residence visa for more than 10 years. Stanford says they're fixing that. Where migrants don't follow the conditions of their visa, she says, I've made it clear to Immigration New Zealand compliance and enforcement actions are a priority.
