We want to be part of the team! Subcontracting, or plant hire, we can help make your project a success.

Subcontract cable laying, trenching or trenchless work. Plant and operator hire options are also available on most of our plant.

All our plant and equipment is managed and maintained by Blackley Equipment Ltd and Blackley Equipment Hawkes Bay Ltd.

The Blackley Group have invested heavily in a wide range of trenchless equipment. From small to large, we can cover most project needs.
