More immigration calls overturned in 2018 than any other year

Immigration New Zealand's decisions have been successfully overturned more times in the last year than at any time in its history. An immigration lawyer says staff turnover, delays in processing and heavy workloads have led to inconsistencies and mistakes in visa processing. One immigrant, who successfully appealed, says he knows people who have had to leave the country as a result of a bad decision. Gill Bonnett reports.
