Thank heavens, then, that sense has finally prevailed and the Clive to Hastings stretch of SH2 has been designated an 80km/h speed zone.
This column called for a speed restriction on this notorious section of road in 2010 following a New Zealand Road Assessment Programme report which showed it was one of the worst stretches of rural state highway for crashes in the country.
The wheels of bureaucracy turn slowly but the New Zealand Transport Agency has now consulted with everyone it needed to and made the change.
This will be a huge relief to staff and the parents of pupils at Mangateretere School, who, with good reason, have long feared an out of control car will smash into the school grounds.
The inappropriateness of a 100km/h limit is not confined to the Mangateretere stretch of SH2. There are businesses, intersections and residences all along the highway. Residents got up a petition calling for a reduction in the speed limit in 2006.
The next step should be to remove the state highway designation from the Clive to Hastings road so traffic-calming measures such as roundabouts can be built where needed. Because while this stretch of roading might be busy it is certainly not built for speed.
