But as cars have become more efficient, the number has been growing at a much higher rate than the tax take. Something has to be done about this situation, as it is not sustainable long term.

Fuel has got a lot more expensive around the same rate that cars have gotten more efficient, so it kinda cancelled out since the tax is a % of the price... They could also just adjust the tax...

True, fuel efficiency meaning less petrol consumed & lower tax take is an aspect i'd not considered. Has that trend continued since the EV subsidy was canned? I'd expect the uptake of EVs was counterbalancing the fuel inefficiency of the ever larger Ute, and without a subsidy the EV sales dropped.

In any case, part of the massively increased cost in road construction is due to having to build roads that can safely take the weight of the trucks getting larger since the National legislation changes in 2014; those heavier trucks travelling faster is also part of the reason why there are more pot holes. Yet the operators that have gotten extremely wealthy have never had to pay their way to use the roads. Unlike the various rail / coastal shipping operators who could transport far more freight far more efficiently (if less time flexibly).

Utes and any diesel powered vehicle, already pay road user charges.

The fleet has been getting more efficient over time, this is expected.

As a side note, the damage that a vehicle does to the road rises at the 4th power of weight.
So a vehicle that is double the weight does 16 times the damage. Using a 1200kg car as the baseline with a damage factor of 1, a 50T truck will produce a damage of ~335,000 (assume that the weight is evenly distributed across the 9 axles)

Oh yeah duh, probably aren't any modern Utes that are petrol nowadays - though i'd guess some medium-large SUVs probably still are.

The damage thing is mad huh - which is why the way RUCs are charged on heavy freight is (last time I looked anyway) such a heavy subsidy to that industry.

[–] Dave 2 points 2 months ago (1 children)

RUC is weight based. If the weight is an issue, shouldn't the government just increase the cost of RUC in the higher bands?

[–] TagMeInSkipIGotThis 2 points 2 months ago (2 children)

Here's the thing. Freight transport is obviously important to the country's economic activity, so i'm actually OK with some form of public funding for road freight.

But I also think the heaviest freight would be better off the roads altogether and that in an ideal world long distance freight would also not be transported the length of the country. This could make roads safer, cheaper to build and reduce emissions by using more efficient vehicles.

Now, that implies that yes, low RUCs on heavy trucks is a problem, but its a multi-faceted one and the problem is that our current government's transport strategy just roads roads roads.

Isn't you and I driving also important to the country's economic activity? I drive to work, I drive to the stores. I drive to the gym and recreational activities. That's all economic activity.

[–] Dave 2 points 2 months ago (1 children)

If the government wants to go the open market route, shouldn't they increase RUC on heavy vehicles, making it user pays? Then alternatives to road freight become more cost effective.

[–] TagMeInSkipIGotThis 2 points 2 months ago (1 children)

There's two ways to achieve it; re-introduce the legislation (I think) from prior to the 80s that limited the maximum distance freight could be transported on road. If I recall some documentaries i've watched correctly it was removing this restriction that made road transport competitive with rail in the first place and precipitated the decline of TranzRail.

Or, as you say, charge all forms of transport the full cost of provisioning it which would immediately make road transport very expensive. The problem is that would probably cause an immediate inflation bump as a mode change like that really needs careful panning and transition.

I feel like I heard of a Labour plan to build rail hubs. Infrastructure like that is expensive and risky for private companies (because what if there are no customers?), but if the government set it up (say, one near Auckland and one near Wellington), and organised the rail freight between, you could have a really nice rail system set up, with trucks handling just the first and last stretch.

[–] absGeekNZ 2 points 2 months ago (1 children)

If it follows SH1 (mostly) that would be a great thing.

I would love to be able to have passenger terminals available to travel to Wellington / Auckland

[–] Dave 1 points 2 months ago

I was thinking freight hubs installed on the existing train line.

Wellington/Auckland passenger rail is already available, but it's marketed to tourists and has a price to match, at $250 per person one way. You'll find flights for half that.

[–] TagMeInSkipIGotThis 2 points 2 months ago (1 children)

Yeah, and if well designed it potentially is an investment like electrifying steel furnaces. Anything we do that has a big impact on reducing emissions is likely a good thing.

[–] Dave 1 points 2 months ago

Maybe we could get the main line from Auckland to Wellington electrified for heavy freight? Ok now I'm just drreaming.
