A rental car company in Christchurch is charging the parents of two men killed by collapsing ice at Fox Glacier, $700 for the return of the vehicle.
Ashish Miranda, 24, and his brother, Akshay, 22, were buried by ice and rock, at the toe of the glacier on 8 January.
They travelled there in a car rented by their cousin.
But the keys were buried with the men and the car had to be towed back to Christchurch on Tuesday.
The tow cost around $700 and company director Edwin Chan says that cost is a burden for the business, NZRCS. He intends to charge the dead men's family for this.
But he says he will not charge a fee for the late return of the car which should have been returned on Sunday.
The Rental Vehicles Association says the situation highlights the importance of travel insurance.
