Is any road safe from Waka Kotahi?

The Herald reports:

Another 2500 kilometres of road has been identified as having speed limits too fast to be safe, according to Waka Kotahi. …

The agency has earlier marked 7465km across New Zealand where the speed limit is higher than what it calls “safe and appropriate”.

This equates to more than 85 per cent of the country’s roads.

So the Government wanted to reduce speed limits on 85% of NZ’s roads and now has found another 2,500 kms it thinks should have a lower limit.

I think we can conclude that the Government considers every road in NZ as unsafe, and they all need to be reduced to say cycling speed.

Presumably they want to turn the clock back to 1973, when the speed limit was cut from 100 km/hr to 80 km/hr to save oil. Or perhaps they want to go back to the 1930 speed limit of 48 km/hr?
