Spanning 6.1ha on Mangatawa land parallel to Tauranga's Eastern Link, the 18,200sq m freight terminal is the largest transport branch for the company's New Zealand network.
This evening,
the facility was officially opened with formalities including a powhiri and special haka on behalf of Mangatawa.
James Tapiata's large whale carving depicting a Māori legend of the arrival of a family of whales known as Mangatawa, Hikurangi and Kopukairoa, which stretches as tall as the ceiling in the entrance of the new facility was also unveiled.
Mainfreight's founder and chairman Bruce Plested said he was proud to officially open the facility.
"It is just fabulous. It has got everything that we know and ever learned over 42 years that should be in a depot."
That included solar panels that lined the roof, a truck wash station that recycles 80 per cent of its water, and electric vehicle car parking stations.
"We are just getting better and better at what we do. It's all a team effort."
The words 'Special people, special company' are printed on the building's exterior - something Plested says was a statement they came up with back in 1988.
Plested said opening a multi-million-dollar global facility, the largest in its New Zealand network, in Tauranga was important.
"Tauranga is a growing place and it has become New Zealand's largest port. Of course, we do sea and air freight, warehousing, domestic transport by rail and road and in Tauranga we have about 22 truckloads a day of freight coming through here.
"It is a big spot for us and a very important one."
