"It is important that motorists know that the big rig coming down the road is safe and roadworthy and the driver is sharp and alert. We want all road users to complete their journey without incident and get home to their friends and family unharmed," Mr O'Brien said.
Some of the heavy vehicles stopped were showing signs of poor maintenance with 35 vehicles classed as being unsafe and ordered off the road while defects that required immediate attention were identified in a further 13 vehicles.
The operation was undertaken with other road policing partners and, over the four days, checkpoints were held in Blenheim, Ashburton, Christchurch City and North Canterbury.
Across the four sites, 33 infringement notices were issued in Christchurch City, 31 in Blenheim, 21 in North Canterbury and 19 in Ashburton.
