Mike Haturini - Complex Builders

Director – Mike Haturini

I grew up in Mangere, attended Onehunga High School where I discovered my passion for building. I was chosen and given a scholarship to complete my apprenticeship with the largest construction company in New Zealand Fletchers Construction.

While doing my time I worked on large scale projects where I learnt how important Budgets, Communication and Project Schedule’s are for clients. I also learnt  many valuable construction methods used all over New Zealand.

After completing my study I worked on apartment blocks and subdivisions where I made the decision to start my own business so that I could work intimately with clients to provide and control quality service and work I knew I could produce. It has always been a priority of mine to  provide a great service and quality product I  believe that communication is the key to an efficient and effective build process.

I am happy with my profession and enjoy all aspects of  my work.

I enjoy meeting people, the change of environment and scenery from job to job.

In my spare time I like to get outdoors and go fishing, hunting diving. Providing for my family is my motivation.

My wife and I enjoy exploring new places both nationally and internationally and travel as often as we can to see and experience as much as we can. We have a 2 year old daughter who keeps us on our toes she is our first child and our experience so far has been awesome.
