Tuesdays and thursdays are decent meet nights where I am now (just a suggestion) but in Otago obviously avoid town cruises on thursdays unless you like having drunk students around your car...
Another suggestion would be dinner cruises. We do a meet every week here (alternating Tuesday Thursday) and the half way point of every cruise is a pub/fast food/fish and chips for a feed and some more of the social side of things. (Admittably Dunedin is somewhat lacking in that area depending on where you go I guess).
Sorry for jumping in the thread whilst not being in Otago any more but meh, suggestions all round, it\'s only the poll that counts I guess.
