A herd of new milk tankers for Fonterra.
The co-operative's renewing 79 of its fleet, as part of its ongoing upgrade programme.
An example of the massive mileage the vehicles rack up is the tanker driven by Darfield's Rowly Stewart.
At a rate of 500 kilometres a day, it's done the equivalent of driving to the moon and back, twice, over the past six years.
Rowly Stewart says it's always interesting getting a new tanker.
"It's a bit like with your car, you get a bit attached to your car and sometimes if it doesn't do what it's supposed to, you talk to it, and sometimes you pray that when it does good. So just getting used to this one now, it's clocked up just over 70,000 kilometres already - since August."
Rowly Stewart says his truck is a great office, because the view is always changing.
