As well as beating the Aussies, the number of Kiwi properties receiving awards increased from six to 13 since 2016.
"The jump in award recipients is a sign of the growth in quality Kiwi accommodation and how owners are making the most of the tourist boom," Luke Ashall, Booking.com country manager for New Zealand, said. "This is obviously great news for the properties that receive awards as well as the New Zealand tourism industry and economy."
Properties from all around the country were recognised, including Marlborough, Wellington, Russell, Auckland, Hokitika and more.
This year has also seen an increase in the variation of property types achieving the perfect 10 score. The winners this year included B&Bs, holiday homes, a guest house, country house apartment, lodge and a tented camp - reflecting continued global increase in the demand for holiday rentals.
Carmel, owner of award-winning property, Rosebrook Country Homestead in Drury, explained what it meant for her property to win a Guest Review Award.
"We've put a lot of hard work in to ensuring our guests have an enjoyable stay with us. It largely comes down to being welcoming and making people feel well looked after.
"Booking.com acts as a great platform for us to showcase our property and connect with potential customers from all over the world. Being one of only 13 New Zealand properties to receive an award is a huge honour," she said.
