The election has spooked some US buyers into looking further afield for houses.

Americans have picked out their exit route in case of chaos after this year's election - and it may be to New Zealand.

Realestate.co.nz is reporting a big increase in the number of visits to the site from US-based users.

For the two days before the election on Wednesday (NZ time), there were 141 per cent more visitors to the site from the US than there were at the same time the year before.

"Americans may be weighing up their options as the US election comes to a conclusion, and there are clear indications they are increasingly looking at New Zealand as a viable option," said chief executive Brendon Skipper.

"Interest from US citizens in New Zealand homes for sale has catapulted in the last two days."

He said the month leading up to the election had been busier than normal.

Between October 9 and November 8, the number of America-based users increased by 51 per cent compared to the same time in 2015.

"On average, they are spending almost seven minutes on site, indicating they are having more than a casual glance," Skipper said.

"Search terms suggests that they are looking at their options across the country, but perhaps with a skew towards Auckland."

Most of those searching were younger - almost half in the 25 to 44-year-old age bracket.

Trade Me Property also noticed an increase.

"We see a large number of US-based views throughout the year but in the last three days there's been a 200 per cent jump in views compared to this time last year,' a spokesman said.
