DPF has produced some statistics on written questions in this term of Parliament. I did a similar exercise last year (covering three years, not one), with similar results - there are a handful of top questioners (Tony Ryall and Katherine Rich rate consistently highly), followed by a long tail of those less active. United Future seems to be asking more questions than the Greens this term, but otherwise the party order is pretty much the same.
DPF's data is however incomplete - he's left out the results for the leader of the opposition, (National's) chief whip, and deputy speaker. For the curious, their numbers are:
- Lindsay Tisch: 5
- Don Brash: 1
- Clem Simich: 0
DPF justifies this omission on the grounds that these three MPs have significant other duties. This is fair enough in the case of Simich, but as for the others it is worth noting that DPF has listed the stats for every other (non-government) party leader and whip. The inescapable conclusion then is that he has omitted the data just to avoid making two major players in his party look bad.
