So my question to the Minister in relation to that increased threshold is whether it takes into account the possibility of inflation, and, if not, why not? I have a question too about whether any thought has been given to the possibility of the exchange rate—that is to say, the New Zealand dollar as compared with overseas currencies. New Zealand families are not immune to the fluctuations in the exchange rate. It's not a particular area of expertise of mine, but I will note, of course, that in a pretty volatile global environment—I mean, New Zealand, I suppose, is doing its best to insulate itself from that by not entering into any new trade agreements, but that's more in the category of cock-up than conspiracy, or perhaps accident rather than design. But, in any case, the reality is that it is at least theoretically possible that the exchange rate of various other currencies that are relevant to New Zealand families, directly or indirectly, should be considered, in my submission, and I want to know if the Minister has given any such consideration.
