The warranty of fitness for a particular purpose is implied when a buyer relies upon the seller to select the goods to fit a specific request. For example, this warranty is violated when a buyer asks a mechanic to provide snow tires and receives tires that are unsafe to use in snow.

This implied warranty can also be expressly disclaimed by name, thereby shifting the risk of unfitness back to the buyer. Warrant of Fitness or WOF regulations are changing. Vehicles first registered before 1 January 2000 will continue to require a WOF every six months, but newer vehicles will be changing to require one WOF per year for the lifetime of the vehicle.

Until then, vehicles remain on their existing inspection frequency.Fully qualified Warrant of Fitness inspectors. All WOF inspectors are fully experienced in vehicle mechanics and servicing. They complete regular updates and liaise with New Zealand Transport Agency (NZTA) on all WOF requirements.
