Mr Kapila said after his release yesterday that life had been "really bad and hard" in prison and he was happy the family was together again.
Speaking in faltering English through an interpreter, he agreed with immigration consultant Tuariki Delamere that the forced taking of his wife's fingerprints turned out to be a blessing in disguise.
As a result of the investigation, Immigration New Zealand has agreed to enter a process whereby the family can lodge an appeal on humanitarian grounds to be allowed to stay in New Zealand. The appeal will be heard within three months by the Immigration and Protection Tribunal.
Mr and Mrs Kapila used their Tauranga-born citizen son Abhay, 9, in a desperate high-stakes gamble to avoid being deported back to India, saying they would sooner leave their son behind to give him a brighter future in New Zealand than condemn him to life in a Punjab slum.
Mr Kapila said their daughter Simran, 14, a pupil at Te Puke High School, could not remember life before New Zealand.
The family arrived 10 years ago and spent years paying an Auckland lawyer to act for them to secure permanent residency. It turned out their last visa extension application was filed in 2005 but they believed the lawyer was still acting for them up until last year when Immigration raided their Te Puke home.
Mr Delamere said that after the investigation findings were released last week, Mrs Kapila had decided that she did not want disciplinary action taken against the police and immigration staff.
"She realised that they were just trying to do their job and, even though they had caused her injury, they had acted in good faith."
He said that Mrs Kapila was grateful for the personal apologies she had received from police and Immigration New Zealand. They accepted that there had been no malice when the police, acting on instruction from an immigration official, had forcibly taken Mrs Kapila's fingerprints.
