Immigration New Zealand is fast-tracking the visas of overseas family members of those killed in the Christchurch shootings. They say they've issued more than one-hundred and have set up a special processing system to handle all the requests. Some relatives of victims say they need their families to stay longer than a visitor visa allows and are asking for special dispensation from the Minister of Immigration. Peter Elms is Assistant General Manager of Immigration New Zealand. He talks to Susie Ferguson.
