The main thing is.....if we have better terms of trade then our currency is more sought after....and its value would tend to rise. That gives is all more buying power. We are all better off.

If our dollar increases, yes we get cheaper imports, but demand for those imports increases.

It also hurts many exporters, so our export revenues decrease significantly.

Hammerer:

It sounds good replacing 56,000 vehicles a year but how many years will it take to replace the existing fleet?

Assuming the entire light vehicle fleet can be functionally replaced with EVs (it can't, yet), that would take about 60 years.

But over that time wewould expect improvements in EV tech to cause the rate of uptake to increase rapidly. We have an average fleet age somewhere in the teens. So I would say best case scenario is somewhere around 20 years.

Something that concerns me is there are few or no EV replacements for the most popular vehicles sold new - utes, heavy vans, larger SUVs.

Hyundai will be releasing the Kona 64kWh EV here any day now. Jaguar has the e-Pace (no, I'm not buying one of them either, but I see plenty of luxury cars on the roads around here so clearly someone can). There's the Tesla Model X, and then, there is the Bollinger B1 which I covet relentlessly but probably won't be able to afford until it's been out here for a few years anyway.

The rising cost of petrol is one of the main reasons we recently bought a diesel (2014 Mazda CX-5 2.2L turbo diesel). $85 to fill up compared to $130 in our Mazda 6 (95 petrol). Even with RUC I estimate we'll be about $1k better off per year.

You would think that with the high price of petrol that people would drive a little bit slower and at least within the speed limits. I was driving at the speed limit the other day and two vehicles ripped past me going about 10kmh over the limit and using a lot more petrol to cover the same distance!

For all the noise about petrol price increases, petrol still represents a very good value product for most people.

Hence you see people doing lots of complaining, but not much actual behavior changes / fuel conservation.

Consider your example. If driving 10km/h faster takes your car from say 7L/100km to 8L/100km, that is only an extra $5 for say an Auckland to Tauranga trip. If that extra speed saved you 12mins over the entire trip, then (ignoring the law breaking & safety aspect), anybody who's time is worth more than $25/hour could justify it financially...

On the other hand, some people just like to go fast, and other have no idea that higher speeds cause areo drag to go up by the 4th power.

Were you talking indicated speed or actual speed?

Depends if your time is more valuable than fuel. I spend 20 hours a week in the car. If someone wants to drive at 85kmh that's fine. But I don't, so let me past!

The bigger problem with petrol price rises, is the knock on effects with everything going up in price, as everything has to be transported. It seems for a long time everyone wanted the NZ dollar to weaken, so NZ would earn more for their exports, such as milk. Now it has gone weaker, it means imports are now higher, including fuel. There is no way to keep everyone happy.

Generally, exporters are very happy when the dollar is lower as they increase their profit and makes their products more competitive. Importers and consumers are not.

This revaluation of the dollar is really about the strength of the US dollar so even though oil is traded in US dollars it may not be such a big factor, perhaps more that oil itself has risen in US dollar value.

And the corollary to that is our dollar hasn’t changed much relative to our key export markets so we haven’t gained much from a lower dollar.

Perhaps they are trying to get to a service station before the price increases again.

Indeed. This is one reason why many things are much cheaper in the USA, where they don't use petrol as a source of government revenue to such a vast extent as Europe and here.

Petrol always seems cheaper in Australia; I presume they deal with it slightly differently? Would that system work here?

They don't use anything as a source of government revenue. That's why their debts are in the tens of trillions of dollars and climbing every day.

Except that there will be a balance point, at which going slower won't actually reduce your fuel usage. And which in fact will cause you to use extra fuel.

If driving slower means that the gearbox has to run in a lower gear, or the lockup clutch has to disengage. You will almost certainly be using more fuel, despite going slower.

On a lot of diesel cars and older petrol cars. They typically have only a narrow RPM band where the engine operates at peak efficiency. So the most efficient speed will typically be whatever speed keeps the engine in that band while in top gear.

Was shocked to see the price locally ("the national price") went down 3c yesterday afternoon - now $2.459
