Pearce said in just over 24 hours, the 1983 20 D Massey Ferguson tractor, or Bert, had stopped only for refuelling.
The men were welcomed back to Invercargill by a group of friends, family and well-wishers on Tuesday afternoon.
Only two liquorice allsorts were left by the trek's end.
"The liquorice allsorts were there just so we could have a nibble when we were driving. That just keeps us awake and gives a wee bit of an energy boost."
Listen to Jamie Mackay interview Fraser Pearce during the trek on The Country:
The group left from E. Hayes & Sons in Invercargill and drove to the Christchurch Charity Hospital.
Based on the Christchurch operation, the Southland version would offer treatment to patients referred to them within the Southern DHB area who are unable to access treatment through the private or public health systems.
As of Tuesday afternoon, an initial estimate showed the trek had raised nearly $7600.
