Politicians, Elections in NZ

I've discovered the Department of Personal Opinions website and it is quite an interesting one.  I've done a cursory look and it is a good site to start with in understanding NZ politics.  I guess just like any politician in any country, they are always busy, well some of them are while others appear to be, and others seem to be.  I've emailed a number of them in Parliament with some graciously answering my email within 24 hours (which is good email etiquette really), a few answered by their staff, and the rest totally ignored.  It's not easy to get their attention, even during election time, specially when you're not within their media radar.
