From Tuesday 4th August 2026, Simcox Construction will become Isaac Construction.
Simcox has a long and proud history in Marlborough – one we’re committed to carrying forward under the Isaac name. As part of bringing our business together under a single, recognised brand, we will begin operating as Isaac Construction from this date.
Our experienced earthworks, roading and quarry teams remain unchanged, continuing to deliver the high-quality work you’ve come to expect. Just as importantly, our commitment to our clients, communities and the Marlborough region remains the same.
In practical terms, very little will change for you. You’ll continue working with the same people, receiving the same level of service and dealing with your local team. Existing contracts, arrangements and points of contact will all remain in place.
Invoices will continue to be sent to and from accounts@isaac.co.nz, and our phone numbers will stay the same. From 4 August 2026, you will notice our email addresses change.
We look forward to continuing to work alongside you as Isaac Construction and thank you for your ongoing support.
If you have any questions, please don’t hesitate to get in touch.
