Pieter Botha
Business Unit Manager
Projects and Gunac | Waterproofing Specialists
After 22 years of managing my own construction company in South Africa, I decided to make New Zealand and Access | Partners in Property my new home. Starting at Access as a project manager was my opportunity to make a difference in the NZ construction industry. Eight months down the line, I grew into the role of Business Unit Manager, leading and facilitating the dynamic Gunac and Projects Team.
When I am not supporting my team to deliver the quality work we provide, you will find me enjoying the beautiful outdoors and magnificent fishing opportunities.

Senior Project Manager - Liquids
Arriving from South Africa last August in 2023, I bring a wealth of experience to the liquids department at Gunac. For 14 years, I owned and operated a small waterproofing company, honing my skills and expertise in the field. Now, as Senior Project Manager, I tackle the daily challenges of a new market, diverse products, and ever-changing weather conditions with enthusiasm.
Leading a multicultural team, I value the diversity of perspectives and experiences. Outside of work, I share my passion for adventure sports with my wife & sons, such as mountain biking, motocross, and BMX.
