Israeli Gil Ingel sent the Usar team to look for his 22-year-old son, Gabi, who was crushed to death alongside Mr Levy, because he thought the New Zealand-led efforts were incompetent.
A Government investigation, focusing initially on four Israelis in a van in the CBD at the time of the earthquake, found no evidence of links to Israeli intelligence agencies.
One of the four, Ofer Mizrahi, was killed; the other three left the country within 12 hours, attracting the attention of New Zealand officials which led to the investigation.
The Israeli Embassy yesterday confirmed that Mr Mizrahi had only two passports - one Israeli, the other European - and they were both handed in to the embassy by his friends before they left New Zealand.
