    Maybe in NZ, as they are *allowed* to do more 'unqualified' work that they feel more comfortable asking for advice, and hence there is more shared expertise, and so are less deaths than in Oz, per capita?

    would be good to see more recent data too.

    That's about as up-to-date as you'll get. Coronial investigations can take a year or two to make a finding, then it's another year till it gets added to the actual death stats. The latest Cause of Death stats can be found here: 3303.0 - Causes of Death, Australia, 2012 , and you can compare them internationally by using the ICD-10 code for the underlying cause.

    Realistically, the NZ numbers are already down at statistically meaningless levels at a yearly basis, and you'd need to do time series analysis to identify trends.

    HI
    A look at graph 1.5 gives a better indication & NZ does not show up too good in THAT.

    Graph 1.5 is a three year moving average - and moving averages are forecasting tools, but when you are dealing with small numbers, this sort of statistical analysis becomes meaningless. (basically, small changes have their effects magnified).

    If anything, graph 1.5 indicates that the rate in Australia is increasing quite rapidly.

    The raw data (Table 4) shows that Australia's rate was 7 in 2007-08, jumped to 13 in 08-09 (an 85% increase), and jumped again to 25 in 09-10 (92% increase), so using the three year moving average trend, you'd expect a 2010-11 figure of around 47, while NZ should remain stable (5, 3, 3 for the same period, so you'd expect 2010-11 to be 3 again).

    Seems like NZ's plan is better than Australia's then?

    Those who want to ignore the science are increasingly alone. They are on their own shrinking island.

    NZ people live on the edge whereas Australian people are more nanny state driven. So who ends up with better common sense!

    IMO It's high time that these protected industries were deregulated somewhat and that NZ model seems to work.

    If you look at the 5 year average, the NZ death rate is quite a bit higher than Australia, with an average of 1 death per year for every 916,000 population.
    In Australia it was 1 death per year for every 1,279,000.
    Most of these deaths were caused by misuse/interference with equipment or wiring.

    What this is telling me is, in order to reduce these deaths, we need more education to prevent DIY misuse/interference with equipment or wiring.

    There are not a lot of data presented. Looking at the fatality data from nz year by year.
    The histogram tells a fairly good story:
    histplot.png
    One can tell the majority of the fatality is between 2 and 4 per year with a total occurrence of 8 years. The average is skewed by some high fatality rate at the far right. And before we jump to the conclusion that 5 year average tells some kind of story, we should know that those high fatality rate which influence the 5 year figures so much are outliers and knowing what happened that contributed to those figures would be a good start.
    Next if we divide the oz figures by 5, we can compare the nz and oz figures side by side with the following boxplot
    rplot01.png
    As you can see the OZ has a slightly higher average number compared with the NZ figures, but they are by and large similar. A statistical t.test also reveal that there is no reason to believe that the mean fataliy figures are any different between the two countries.
    Which should also mean that do-it-yourself electrical work does not result in higher or lower death rate based on statistical data presented.

    The long term averages (deaths per year, 17 years of data) for Australia and NZ are 28 and 3.

    The population disparity between Aust/NZ is a factor of 5.1 (22.68 million vs. 4.433 million), so if Australia's electrical safety regime was as effective as NZ, then the 17 year average for Australia should be about 15, rather than being nearly double that at 28. This suggests that Australia's system is, in internet terms, epic fail.

    You could then compare this to other countries, such as the UK, with a population of 63.23 million people and a 2010 death rate of 28...adjust for population and you get 10 deaths per year, which suggests that the UK model is safer still.

    For some people yes but others need protecting from themselves.

    There was a death from electrocution in my area a few years ago when one of the local druggies tried to wire up his hydroponic dope crop. more education may not work in all cases.

    I have always found that people who don't understand electrical work stay well enough away from it, don't even contemplate it.

    And there are the others who rely on Google for all their knowledge.

    They have to connect up the heating lamps so it doesn't register on the meter so they have to break into the consumers mains that can't be isolated.
    Hell ain't full yet so there is more room for the hootch growers.
