Hello all. First visit to NZ, 30 days. I would like some help with understanding the pros and cons of how to handle the insurance for a camper van rental. They have insurance and a bond required(which I understand), plus we can optionally get whats called "excess reduction". It appears that this "reduction" applies to liability or deductibles in the event of a catastrophic event (?). But this fee is not refundable, and basically triples the insurance. So why should I do this? Are windshields and tires (tyres) commonly damaged, or is theft/vandalism common and I am best to get more insurance? No offense to my Kiwi brethren, just trying to be frugal as much as I can but not making a poor financial decision.
I would like some help to decide what is the best option, looking at the relative merits of this excess reduction, bonds, etc. I am pretty good about avoiding accidents in other countries, but no guarantee.
Thanks in advance.
