Immigration Minister Erica Stanford will introduce legislation on Wednesday, saying the changes will give authorities "proportionate tools" to manage immigration risks while ensuring the system is fair, functional and effective.
The bill would extend from 10-to-20 years the period during which a resident can become liable for deportation for serious criminal offending, raise the maximum sentence for migrant exploitation to 10 years from seven, and widen powers to act on false or misleading information supplied during the immigration process.
The bill will have to pass three readings in parliament, but as the government has a majority it will likely pass.
The move reflects a broader push by governments globally to strengthen immigration and asylum systems as they face political pressure to deter abuse, deport non-citizens convicted of serious crimes and preserve public support for refugee protections.
Alongside the bill, the government will table a parliamentary paper proposing further asylum changes, including allowing officials to consider serious crimes committed in New Zealand before refugee status is decided, according to the statement.
Stanford said 14 known refugee claimants had been convicted of serious offences in New Zealand, including murder, serious sexual and drug crimes and arson.
Other proposals would let authorities move more quickly against claimants deemed to be acting in bad faith, including those who deliberately seek publicity to bolster asylum claims, and against those who fail to attend biometric appointments without good reason, the statement said.
