Jay told the Herald that on average about 700 New Zealanders booked cars through EuroLease a year.
She said that anyone who had a booking through a travel agent should contact them to get a refund.
Although Eurolease is opting out, another New Zealand firm, Peugeot Drive Europe, is still taking bookings.
General manager Delwyn Sinclair said website traffic had trebled since Eurolease pulled out.
It is holding deposits of $300 for each customer in credit for the next two years.
She said normally about 1000 Kiwis booked cars through Peugeot Drive Europe a year.
There was a small ''hard core'' of clients who were going ahead with their European holidays this year.
Many of those had houses in Europe where they could stay for several months which made the cost of quarantining on their arrival back in this country less of a burden.
She hoped business would pick up quickly once health concerns and travel restrictions eased and already had inquiries around the Rugby World Cup in France in 2023.
Under the lease scheme visitors from non-European countries lease a brand new car from manufacturers.
After three weeks to several months driving it was sold as a near-new car to French citizens for around 30 per cent less than the showroom price and helped support the manufacturing industry.
