New Zealand's government is set to introduce legislation to tighten deportation, asylum and immigration enforcement rules. The changes are intended to tackle serious offending, migrant exploitation, and bad-faith claims. The bill would extend from 10 to 20 years the period when a resident can become liable for deportation for serious criminal offending, raise the maximum sentence for migrant exploitation from seven to 10 years. It will also allow authorities to act on false or misleading information provided during the immigration process. The move reflects a global push by governments to strengthen immigration and asylum systems.
