Good planning prevents costly surprises.

One of the biggest issues we’re seeing across the trades is unnecessary variations, often caused by a lack of due diligence before work begins.

At Tāmaki Group, we believe proper investigation, planning and communication are key to keeping projects on track and avoiding unexpected costs.

With our in-house drainage equipment, we offer:

* CCTV drain inspections and pipe locating
* 3,800 PSI high-pressure drain jetting
* Pre- and post-jetting video inspections
* Drainage investigations and due diligence

Variations can’t always be eliminated, but many can be avoided with the right preparation.

Our approach is simple: identify potential issues early, document existing conditions and give our clients confidence before work begins.

Less guesswork. Fewer surprises. Better results.

Another quality project recently completed by the team in Three Kings. Working closely with the client and project team, we delivered a stormwater upgrade and sewer extension to service the property extension.

Our scope included the installation of a rockbore stormwater chamber, full property stormwater redirection, and the extension of the sanitary sewer network to accommodate the new building works. We also removed sections of the existing earthenware drainage and upgraded the infrastructure to modern PVC systems where required.

Delivered in challenging ground conditions working with InterRock, this project ensures the property is ready for the next stage of construction with compliant, reliable drainage infrastructure.

Collapsed driveway and post replacement in Hillsborough

After cutting in and investigating, we found a 225mm line had been thrust into the manhole with incorrect benching at the inlet to the chamber. Over time this caused washout, loss of support, and the driveway to slump.

We excavated all unsuitable material, installed compliant backfill compacted in 150mm layers, and prepped for asphalt reinstatement. Also removed further subsided asphalt and replaced a retaining wall post while on site.

We carry out our work to stand the test of time built to last well beyond standard workmanship warranties.

Property in West Auckland experiencing ongoing warranty issues and faulty tapware

After assessing the setup, we found there was no suitable limiting valve installed, putting the system and new fixtures at risk. Worked with the client on a plan, cut in an access hatch through the garage for proper access, and installed a compliant limiting valve to protect the system and ensure warranty coverage going forward.
