He has now spoken exclusively to the Herald.
"Despite everything that happened, I recall New Zealand with much affection. Many times I feel like returning and to continue with what I was doing before the accident. I was there for five months, and know many people and incredible places," he said.
Mr Blake was touring New Zealand with his girlfriend Macarena.
He said the crash and his injuries had been hard for her to deal with but she was "slowly recapturing what she had before the trip to New Zealand".
Mr Blake had spoken with the families of the dead men but was reluctant to talk about it - or how he was coping emotionally. He said he wanted to keep that side of his recovery private.
However, he did talk about his relief and happiness at being able to return to Chile.
"I also started to feel nostalgia for New Zealand and the powerlessness of not being able to go through with what I had planned.
"I remember New Zealand with fondness ... We got to know incredible people and places."
Mr Blake said he still remembered "very little" about the crash.
"I only have a fuzzy memory of a few, very large lights just before the crash, which must have been the truck's lights," he said.
"Before the accident I remember almost everything: the football game and the car trip up to the accident."
When he woke in hospital he could see lots of doctors looking at him.
"They had just operated on my abdomen with a lot of anaesthetic, which is why my memory is not that clear. But I did not understand much. I wanted them to explain to me what had happened," he said.
"My recovery has been good, thanks to the orthopaedic surgeons and trauma team. I feel better and every week have more mobility.
"The injuries that persist today are mainly all the trauma where they operated with plates and screws: the right tibia, the left forearm, the left hand, left collarbone, left shoulder blade," he said.
Mr Blake said he was having physiotherapy and would have surgery to remove a plate in his left collarbone.
