An New Zealand government official revealed that overstayers to the country could be fast track deported should they belong to a demographic group that have previously committed crimes or run up hospital costs. 

Immigration New Zealand compliance and investigations area manager Alistair Murray told RNZ that the country's immigration authorities had been using an algorithm to predict overstaying based on age, gender, and ethnicity modelling data. 

The revelation prompted accusations of illegal racial profiling, forcing the government to admit the pilot programme had been operating clandestinely for 18 months.

The programme was later terminated and a review of government use of algorithms conducted. 

The subsequent stocktaking (pdf) exercise fed into a formal Algorithm Assessment Report by the New Zealand government that made recommendations on the development and use of algorithms, including those introduced to manage migration.
