The vehicle manufacturer will state what each model is capable of towing, this information will be contained in the vehicle owners manual. Each towbar listing also contains information on what your vehicle may be able to tow. If in doubt, please contact us and we'll do our best to locate this information. Whilst this is not a legal requirement we do advise adhering to these ratings. In New Zealand, the law requires that every light vehicle and trailer combination must be capable of stopping within a distance of 7 metres from a speed of 30km/h. In effect, this means the maximum allowable weight of an unbraked trailer is limited by the weight and braking ability of the vehicle being used to tow it. As a guide, NZTA recommends that the laden weight of an unbraked trailer should not exceed three quarters of the laden weight of the towing vehicle - and then only if the towing vehicle’s brakes and tyres are in excellent condition.
