Craigslist
Did you know? Craiglist, the hugely successful free online classified, personal ad and listing service has a Wellington site. As an experiment, a few weeks ago I put up an ad for volunteers for the 'V' 48 Hour Film Competition and got a couple of responses (two more than I was expecting).
There are sections on employment, services, personals, community and housing. All listings are free and you can monitor any section via RSS.
Sadly, the signal to noise ratio is not great as most of the entries are a bit spammy but that should change as Wellingtonians start to use it.
Hmm, just looked at the housing section, and it seems that we have competition with Wellington, Florida.

Hmmn x 2. I've sent off a note asking them why this might be but I suspect posting by bots or posting by stoopid people.
A Low Hum's Blink was in LA with the touring incarnation of Over the Atlantic, who flew to the States without 99 percent of their gear. They sourced everything they needed to play and tour for a song on Craigslist. Granted, it took them a few days to do it, but it works well when you get the location and search down.
http://wellington.gumtree.co.nz/ seems more popular

YAY! I can't wait for the Missed Connections part to start filling up.
