timbosan:

So its more than just $300 for a caravan plug, the above is $500. What's the advantage of that over something like this https://oemaudio.co.nz/electric-vehicle-charging-products/eo-ev-mini-charger-32-amp-black (which is slightly more expensive at $1000+$200 for a cable), but gives a dedicated charger that just need a cable, and its 32amp vs. 16amp. Is it just down to cost or is there more than that?

A 32-amp EVSE not only costs more to begin with but will also require more extensive installation as you probably don't have a 40A circuit in standard house or garage wiring, but you will have at least one 20A circuit already. The $500 one - which I'm pretty sure you could convince the dealer to throw in for free on top of the cost of a $40K+ vehicle - is portable, which means if you are going away on holiday you can use it overnight at a powered caravan site as I have done on two long road trips (and I note the usual objection to buying an EV is "but I drive from Cape Rienga to the Bluff twice a day every weekend so EVs suck!").

I guess it's up to you but personally I would find the extra-expensive one's potentially faster charging of limited value vs. the portability of the other one. A daily 110km commute to Newmarket and back only uses about 22kWh so even the original 8A charger I have sufficed most days. The average daily commute in NZ is less than 25km.

3.3kW, yes, so my 16A charger actually only runs at 14.5A. But all the NZ-new ones will do 7.2kW AC charging. I just don't think it's worth the cost unless you're driving over 400km every day - in which case, I'd love to see your battery after a year!

Some great points there - I didn't even think about Caravan sites. I wonder if they will become 'backup' charging points and potentially make some money on it (assuming they don't all sell their land for development).

My current problem is running the cable for the charger through a window or door, especially when it's raining like it has been or cold. I think a 'caravan' socket gives the best balance between cost and charging speed. Thanks for the advice! Now to find a sparky who can do it ;-)

mikebails: I've got no problem with Mazda providing a smaller battery, but the price HAS to reflect that! If the car was $50k then you could argue that its a good deal, but not at $75k.
interesting if you take the UK price (pre gov rebate, and this includes a 17.5% vat/gst) of £28,500 thats $56,000 a much more reasonable price.

Nice. That's very good news for ex-UK imports. I expect that particular UK model is not Takami spec tho I have not checked.

jarledb: Mazda MX30 0-100: 9.7 seconds.

Yup. This is very conventional acceleration for a medium SUV type vehicle and this provides more predictability for range and economy calculations. I actually think this is an advantage for many drivers.

Yup. Toyota for example does this intentionally with traditional self-charge hybrids to get rock solid predictable fuel economy. I don't know if Toyota does something similar with PHEV-hybrid I expect they do.

Many EVs have 2 charging speeds, slow (at home aka destination charging overnight) and fast (on the road for quick top ups).

The Leaf does 3kw and 50kw.

AC. The Leaf can AC charge at 3.3kW. It can DC charge at 50kW.

For an ICE, yes. For EV? No.

You are really reaching for arguments for the Mazda, aren't you?

Yeah... nah. Look, the Leaf is also not meant to be a sports car but even it turns out a better 0-100 than that. The MX-30 at half the price might be somewhat competitive with the MG, especially if you had concerns over a Chinese-built car. But at a price point where it is competing with cars with a much longer range and/or a much better EV pedigree ... no, it's not even on the radar.
