The car was rented through a online website, called Kayak who then took me to a reantalcars.com site where the final booking was made. The vehicle was advertised at $68 but his turned out to be $68 US more expensive the NZ currency and I was not aware the site was quoting US dollars for people who lived in NZ, which I do. I was then prompted to pay for insurance, at $37 USD approx, I note on the insurance document that the cover was for $73,200.00 USD. When I have rented before the insurance is normally about $30 NZD. I am concerned that I have been charged insurance for the vehicle value in US Dollars ie $73,200 when the vehicle value was in fact $73,200 NZ and the insurance more expensive than required to cover that vehicle. Is something Hertz does to increase revenue, I feel I have been overcharged and it is likely that other people renting through this site have also been overcharged for insurance in this instance. I would like Hertz to formerly acknowledge this incident and to contact me to address this matter. dean.drever@fiziks.co.nz
