If you are thinking of devoting some of Easter to looking for a place to build, the Press has a web page that can help.
Using a map of the greater Christchurch area, you click on the button for the area you want, and are taken to information on subdivisions underway in that area. Click on the name of the subdivision and information about section numbers, sizes, and prices will pop up. The page is here.
When visiting subdivisions don't forget to check out the conditions that apply to the sections - size, design and colour of the house, restrictions on animals and the age of your car, where you can have your barbecue, and what trees and shrubs are permitted.
