Waititi was less than impressed with the listing, however, taking to Twitter to express his anger.
"Please don't pay these blaggards 25k for a car full of rust. Nice timing, btw, cashing in on our film's release," Waititi tweeted.
The listing says the ute is in "original untouched condition showing its age and patina with significant rust around".
"This is a fantastic opportunity given its provenance and connection to a fantastic advertising campaign and an iconic Kiwi especially with a feature length film due out soon. Don't miss the opportunity to secure this investment."
