Are New Zealand holiday homes going global?

It appears that there is an increasing level of interest in New Zealand’s holiday homes from international travelers. Whether it is the possibility of staying on the beach for relatively cheap nightly prices by international standards, or experiencing the Kiwi lifestyle first hand I’m not sure. But more people do seem to be booking a holiday house experience from abroad. I myself have two bookings from Australia and the UK for the Christmas period and have had inquiries from the US.
Is this a general trend through out New Zealand and do we need to change our accommodation offer to cater for these people more effectively? I have a website that promotes my holiday accommodation but it is certainly not designed around a global offer.
This does not appear to be a new topic, as it was covered in 2007 under the title “Holiday Homes gain Market Significance” see the link for details. http://www.scoop.co.nz/stories/BU0706/S00176.htm
Are any other Bach holiday providers experiencing an up turn in this international cliental?
