CHRISTCHURCH, New Zealand — Temel Atacocugu is fed up. Forced to spend most days on the couch in his Christchurch home, he is beginning a long recovery from the nine gunshot wounds he suffered in March when a terrorist fired on Muslim worshipers in this New Zealand city.

Again and again, Mr. Atacocugu has asked when New Zealand’s immigration agency will allow his mother and nephew to join him in Christchurch from Turkey. He needs them to help care for him as he adjusts to his new life. But a month has passed since their visa applications were filed, and no answer has come.

Robbed of what he loves to do most — hiking, fishing, sports, working at his kebab shop — he has started to feel depressed and desperately lonely. “This is really hurting me,” said Mr. Atacocugu, who has lived in the country for a decade and is a citizen. “I am a New Zealander, too.”

Mr. Atacocugu is one of a number of victims of the attacks — in addition to the 51 people killed, more than 40 were injured, some permanently — who say that the New Zealand government has not met the high bar it set in helping them piece their lives back together.
