Retired SWNZ Design (2016)
On 13 May 2016, after nearly eight years of its blue-logo era, SWNZ migrated over to a new design, hosting service, and content management system. For posterity, all the old logos are preserved here, including the Message Board logos that were switched over at the same time as the main website upgrade.
At the time of writing, some pages from the old site are still visible, but they are progressively being ported over and/or updated.
You can also see the 2003-2008 logo design below, and here.
Or, if you want to look way back, the Internet Archive has some fragments of the pre-2003 SWNZ such as the screen-cap below (with, unfortunately, a few missing graphics).
