We have a combined 250 years of experience at NZNI and all our workers are local. Our master craftsman is Sean and he is an integral part of our team.


He will be your main contact with us during the day to day delivery of your contract. Sean is a perfectionist, you will not be disappointed. He has been building since he was 16 years old!
