Funny Crunch, I always thought the Rally Commission was the hardest working. I didn't know it was a contest.
Nevertheless, I'm certain the members of the other commissions would most willing support any presentation outlining the need for the Historic & Classic Commission's continuance. My club's will be including it in their presentations.

The voting issue is a red hearing. Whilst I don't buy into the paranoia of block voting, there is a range of possibilities and no guarantee that any form of proportional voting will deliver any more representative, or better outcomes that what we have today.
At the end of the day, the correct decisions remain the correct decisions and the wrong ones remain wrong regardless of who makes them or how many people support them or otherwise.
The important thing is to have the right people in key roles.

Why does Auckland lack representation? I guess your perception is relative to your view on 'representation', which I've never considered to be a regional matter ... although I know some clubs do. I would rather those representing me have qualified knowledge of my code and the acumen to present it strongly and proficiently in order to ensure the correct outcomes. Where they live is immaterial.
However, the answer to your question is simple – Aucklanders simply haven’t presented the candidates or supported them with lobbying and voting.
