In 2013, Gavin Streeter and Shane Heaton purchased Isaac’s Plumbing, Pumping & Electrical. Back then, the business operated from Waipawa with just seven staff members. Today, Isaac’s has grown into one of Hawke’s Bay’s leading trade service providers, employing more than 90 people across the region.
Due to rapid growth Daniel Pepper joined as a Director in April 2019, bringing with him years of experience within the electrical industry. Matt Gibson joined as a Director in April 2021 as a pump expert, leading our Water Division with extensive knowledge and expertise.
Like Shane and Gavin, Daniel and Matt are Hawke’s Bay locals who work full-time within the Isaac’s business every day.
Fast forward to today, we have new shareholders Braydon Hardwidge, Ryan Hastie, Hunter Burns, Rhys Hardwidge, and William Riddell, reflecting the strength of our team and our commitment to growing the business from within.
We have branches in Hastings and Waipukurau and service all of Hawke’s Bay, including Napier, Havelock North, Hastings, Central Hawke’s Bay, Dannevirke, and Gisborne.
Our people are at the heart of everything we do. We are passionate about attracting and retaining the best talent in the industry and providing the training, support, and opportunities they need to thrive.
We take pride in our responsiveness and professionalism. Our team includes four dedicated schedulers who are ready to organise your job quickly and efficiently, while our highly skilled tradespeople deliver quality workmanship with the highest professional standards.
Safety is a core value at Isaac’s. We employ a full-time Health and Safety Manager and maintain SiteWise Gold Certification and Tōtika Pre-Qualification. We are committed to protecting our staff, our customers, and everyone we work alongside.
Hawke’s Bay is more than just where we work. It’s where we live, raise our families, and build our future. We are committed to helping our staff, clients, and communities thrive through our focus on:

“At Halter, our tower infrastructure has to operate around the clock — 24/7 uptime isn’t a goal, it’s a requirement.
Isaac’s has been an invaluable partner in keeping our systems running smoothly. Whether it’s routine maintenance or an urgent fault, their response times are excellent and their work is thorough.
As a team managing infrastructure across remote locations, having a contractor we can trust at short notice to do the work properly makes a real difference.
Isaac’s have earned that trust, and we wouldn’t hesitate to recommend them.”
