Hmmm...

...does David Farrar really understand the pros and cons of relative poverty measures?

[Update: changed the wording of the post. Also, for what it's worth, I think that my own post is unduly harsh on relative poverty measures, and that CPAG is well within their rights to use them. They're following international norms, the type of measure is eminently justifiable, and DPFs example chosen to illustrate their flaws (where wealthiest 50% of New Zealanders become bankrupt overnight) is an example of a reductio ad absurdum which is, of its own accord, absurd.]
