If you want an auroral forecast, so you know when to look, check the space weather and part way down on the left hand side, you can click on "New Zealand" to see the current auroral oval in our neck of the woods.

You mean you pay them money ? That'll only encourage them ...

Well it looks like Kevin Rudd agrees

You must be thinking of Rikki-tikki-tavi, the mongoose.

Shep. Your second link is broken.

Heartland's claim that the list is a bibliography is patently false. It is a list of names, not of research papers.

check Heartland's references - most of the NZ scientists they cite they refer to as working for the - erm - DSIR? So the scientific papers would be more than 20 years old.
One of the NZ scientists was a student at Waikato and hasn't been seen in the climate science world for 25 years.
And these are the 500 best bits of research that Heartland can find to support their position ? Out of how many hundreds of thousands ? That says a lot for the strength of their position.

Home Solar hot water heating makes a lot more sense than solar electricity generation in the first instance. But if there's leftover, put it into the grid.
I'm no expert, but afaik home solar hot water heating does not produce electricity. It heats water (either directly or, more commonly nowadays, indirectly). It may be possible to use this to somehow generate electricity, but you cannot do it with current home solar water heaters.
So "putting it into the grid" is not a viable plan.
We have solar hot water heating. We turn off the electrical supply to the heater from December to April. For the rest of the year we still need to use electricity to heat our water to ensure that we have hot water on demand (otherwise you could only have a hot shower after a sunny day, which can sometimes be few and far between here in Auckland). Sure the Solar still helps, but ...
No cold showers, no two weeks cut off from the grid while they dig you out from the snow.
... is not valid. And of course, the further south you go, the less sunlight you get, due to the shorter days and the aspect effects (which is why the poles are colder than the tropics).
The people I interviewed worked out it would have paid for itself in 10-20 years.
Before we installed it, I did the math, and discovered that it would never pay for itself, if the cost of the capital is included. It was basically a break even scenario - ie the amount of money saved on electricity bills equals the interest costs on the $7000 required to install it (either paid on borrowed money, or not gained on invested money).
But that was good enough for us.

Hey, that Dan & Dan video is great - so well done - the guy must be a professional !
Now I know the origin of that expression "Right said Fred, both of us together" (always stated tunefully). It was a family saying, usually said when it was time to leave (either from somewhere or for somewhere). The lego version is brill !
Thanks for the enlighten-tainen-ment.

That's not scary. It's scary that it will be enough :P
I almost gave up on the voting public when John Banks got elected Mayor of Auckland.
Then he got re-elected ...
