Best resolved imagery courtesy of NOAA and Landcare Research.
Four NOAA satellite passes are received each day and processed to imagery within half an hour of each satellite pass. There are only four passes per day from the NOAA satellites that cover the whole of New Zealand.
If it's old, try 'Refresh'.

NRL Monterey Global Imagery includes:
Global
GMS-5 VIS
GMS-5 IR
GMS-5 vapour (coloured)
Mosaics and animations can be selected from these.

WMO notes about the satellites including trouble with GMS-5

Notes from NASA incl. "... In June 2001, GMS-5 reduced its southernmost coverage to deal with increased torque in the scan mirror motor at the end of the rotation (probably due to lubricant buildup)...."

For an interesting view of the earth try this Swiss based site.
You will find a composite (73k bmp) surface temperature, cloud, real-time, night-shadow, world map and ability to select various viewing aspects, eg Australasia

GMS satellite images & 12 day mpeg movie are available through this Canterbury University site.

This Australian site provides some very colourful alternatives but tends to trim bits off NZ in their small images.
However, the big versions are brilliant -- if you don't mind waiting for the upload.
