This is not a wisecrack, but why rent in Vancouver for 2 days when the rest of the time would be in Oregon? Is this a special car or agency that will be reimbursed by your company?
With all the stipulations and barriers, it might just make more sense to see if you can return the car to a local office and then hire a vehicle in Oregon instead.
You may need to pay some penalty to return the vehicle at an office away from Vancouver, but the cost may be much less than the added mid-agreement insurance fees.
Then, depending on where/when you fly to New Zealand, you can drive the rental to the airport or take a ride on a bus from Washington State to Vancouver.
