The other main site for jobs in NZ is the Jobs section of trademe.co.nz (who themselves are a pretty cool little company to work far, or so I hear). As far as startups in particular I don't know of any particular website or anything that NZ startups accumulate around, although you might find the NZ Startup Digest interesting (I found it on HN at some stage): http://us1.campaign-archive1.com/?u=92be899ef5a892c60b4a6cd97&id=8c868b3015&e=3d63374b46
I would recommend you also look more specifically into where in New Zealand you want to live, or at least what sort of lifestyle you want. You can easily find a technology job in Auckland or Wellington (startups also tend to gravitate towards these cities), but that comes with higher costs and a certain degree of the rat-race lifestyle. There are small local companies and startups in the provinces, but pay (and costs) will be lower and opportunities are much fewer and far between.
I myself just moved out of the provinces into Wellington, and so far i'm enjoying being in a bigger pool of developers and having more things to see and do in general, but I know people who have made the opposite move as well.
Feel free to contact me if you need more info.
EDIT: Of course if you manage to get a remote job, it won't matter much where you live, provinces or otherwise :-)
It's interesting to contrast this article with the update that was just emailed out to the Uber Oklahoma list:
"Today, we are thrilled to announce that the Tulsa City Council and Mayor Bartlett have paved the way for a permanent home for uberX in Tulsa by signing the recently passed rideshare ordinance."

Edit Here's a copy of the ordinance: http://councildocs.tulsacouncil.org/SuperContainer/RawData//671AOKJV882014103244/14-678-1a.pdf?a=1
There's an interesting series of tweets here: http://us1.campaign-archive1.com/?u=78cbbb7f2882629a5157fa593&id=d6081dc3f9
It outlines a model of "supernova" companies. Companies that initially earmark such a large market that they implode, creating the materials for many other companies. AirBnB for example is just a small chunk of craigslist. Twitter may be in the process of exploding, being unable to capture or tame the reaction.
Before 2012 (when they launched Mandrill) MailChimp used Amazon SES. http://us1.campaign-archive1.com/?u=f7b9ee22124ff6454424dc10c&id=05ee013c3a&e=22702a865e
The Mandrill service is nice, I agree.
Also, MailChimp has a very cool 404 page: http://kb.mailchimp.com/article/transactional-reports-overview/
