The ''high'' risk to each driver using SH 36 reflected the general pattern that personal risk was often highest on lower volume, lower-standard, mountainous roads.
The only other road to show a decline in safety standards was SH 29 over the Kaimai Range, where the overall risk went from medium-high to high.
The stretch of road between Tauranga and Katikati, once nicknamed ''horror highway'', because of the high number of fatal crashes, retained its rating as posing a high overall risk but years of safety upgrades to the road have seen the fatal and injury crashes per kilometre stabilise at a low-medium risk.
