New Zealand Press:

Tauranga Gets Gold! 

“Stonewood Homes, Matamata New Zealand enjoyed phenomenal success with two gold medals in the House of the Year Awards 2008.  They won the prestigious Category Winner and Gold Medal for their entry in the Homes $350,000 to $450,000 category.


“Some of the standout results (they are all standout, these are the real biggies) …

  • I can sleep at night with the knowledge that the projects are where they should be and there is a workable plan for the completion of the home.
  • Clients have a completion date that is real.
  • I have been away on holiday twice since the implementation of our project board, this has been without the need to take a phone for fear of the need for my direction. More importantly upon my return everything is still in order.
  • We have clients that are in their completed homes that consider us their friends after the process of building their home. They tell us their personal news and take delight in us sharing parts of our lives with them. This is a real breakthrough.”

Kevin Norris, Owner Stonewood Homes, Matamata, New Zealand
