Climate Gate Scandal spreads to New Zealand

"Watts Up With That" has this amazing and disappointing discussion of some problems in New Zealand. Here is a discussion from James Delingpole at the UK Telegraph.
The alleged villains this time are the climate scientists at the National Institute of Water and Atmospheric Research (NiWA) – New Zealand’s answer to Britain’s Climate Research Unit. And to judge by this news alert by the Climate Science Coalition of NZ, both institutions share a similarly laissez-faire attitude to scientific accuracy.
Compare and contrast these two graphs and you’ll see.

This is the graph from NiWA’s website, showing mean annual temperature over New Zealand from 1853. Note the dotted straight line showing the upward trend. Worrying, isn’t it? Almost enough to make you fall in love your flickery, yellowy new eco-light bulbs, recycle your kids and commit yourself to a binding agreement at Copenhagen.
Now have a look at this analysis of the raw data taken from exactly the same temperature stations. . . .

The first graph shows a strong warming trend from around 1910 on. While there are some significant ups and downs, no such trend exists in the second graph. Jim Salinger, climate scientist at National Institute of Water and Atmospheric Research and a former researcher at University of East Anglia, is apparently responsible for the first graph. So what is his explanation?

Watts Up has this:
Requests for this information from Dr Salinger himself over the years, by different scientists, have long gone unanswered, but now we might discover the truth.
Proof of man-made warming
What did we find? First, the station histories are unremarkable. There are no reasons for any large corrections. But we were astonished to find that strong adjustments have indeed been made.
About half the adjustments actually created a warming trend where none existed; the other half greatly exaggerated existing warming. All the adjustments increased or even created a warming trend, with only one (Dunedin) going the other way and slightly reducing the original trend.
The shocking truth is that the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming, as documented below. There is nothing in the station histories to warrant these adjustments and to date Dr Salinger and NIWA have not revealed why they did this. . . .

NIWA has this:

Warming over New Zealand through the past century is unequivocal.

NIWA’s analysis of measured temperatures uses internationally accepted techniques, including making adjustments for changes such as movement of measurement sites. For example, in Wellington, early temperature measurements were made near sea level, but in 1928 the measurement site was moved from Thorndon (3 metres above sea level) to Kelburn (125 m above sea level). The Kelburn site is on average 0.8°C cooler than Thorndon, because of the extra height above sea level. . . .
