His father, Dr Blake, has thanked everyone who welcomed his son and girlfriend to the country, gave them work and showed them friendship.
He acknowledged the football team who played against his son and his friends on the night of the crash and "shared with them their last joyful moments".
"Thank you to that other team, the team that rescued Benjamin underneath the distorted irons of the crashed car: the policemen, the firemen, specially those whose name is Benjamin too, and whose father was the ambulance driver that carried my son to Taumarunui Hospital and who I had the privilege to meet a few days ago."
He was also grateful to the medical staff who helped save his son's life and in the rehabilitation care after his surgeries.
"Thank you to all the nurses of the Ward 2 of the Waikato Hospital, who took care of Benjamin, shift after shift, until his discharge and made efforts to understand our English.
"Thank you to Father Gerard, to the psychologist, to the occupational therapist, to the registered nutritionist, to the blood bank and lab personnel, and to everyone who, directly or indirectly had something to do with the cure and care of Benjamin during these 21 days."
Dr Blake said he received "indispensable support" from the ambassador Isauro Torres and the consuls of Chile, Rodrigo Toledo and Gerry Williams.
"My family and I, will never end in our hearts of saying thank you to you all, who were part of Benjamin and Macarena's stay in New Zealand and the returning to life of my son Benjamin."
