Louis' second operation was to fuse the C4 and C5 vertebrae in his neck, which also meant doctors were able to take the halo off his head.
Mr Grindrod said his son was doing amazingly under the circumstances.
"With the aid of a walker, he is able to walk around now. He had his first steps about a week ago."
Mr Grindrod said the feeling on Louis' left side had come back, although it was still much weaker than his right.
Doctors had told the family Louis would need intense rehabilitation over the next four to six weeks before he could be moved back home to Tauranga.
Mr Grindrod said many of Louis' friends had made the trip to Auckland to visit him.
"The support in Tauranga has been amazing, that has been a huge help. It has helped us to see the light at the end of the tunnel."
Mr Grindrod said doctors were hopeful of a full recovery.
"It might take up to 12 months, but to get back to day to day living hopefully a couple of months. Getting his full range of movement back, plus his balance will just take time."
Things could definitely worse, he said.
"We are sitting here in the spinal unit and there are people a lot worse off than Louis is and we are thankful each day for that."
