We’re proud to see our Hydroflow branding out on the road with Tutill Carriers supporting deliveries across the Auckland region.

This truck has been busy on-site, moving ductile iron pipe where it’s needed most and helping keep projects running smoothly. This week alone, it’s delivering 40 tonnes of ductile iron pipe across multiple loads — a great example of the scale and coordination required behind the scenes.

Reliable supply, strong partnerships, and getting product to site when it matters — that’s what keeps infrastructure moving.
