Walk Score describes areas receiving a score between 90 and 100 as "a walker's paradise". Areas with scores between 70 and 89 were also very walkable, and most errands there could be accomplished on foot.
Homes.co.nz spokesman Jeremy O'Hanlon said suburbs with the highest walk score often had the higher value estimates. They were typically in the central suburbs, but there were exceptions.
Property Brokers regional manager Paul Whitaker said walkability was something people considered when buying a home.
Older people often liked to be within walking distance of shops.That affected house prices because it increased demand.
School zones were also very important to families.
"To get into the good school zones now, one street over or one street out can make a difference in sales price as well."
Walk Score analysed hundreds of walking routes to nearby amenities with points awarded based on the distance to the amenities in each category, according to the website.
Amenities within a five-minute walk were given maximum points. No points were given after a 30-minute walk.
Walk Score also measured pedestrian friendliness by analysing population density and road metrics such as block length and intersection density.
