[GRASS-user] Projection of latlong sites file doesn't work

I have a file in the following format:

-45.075000,170.975000,80.173343
-45.025000,170.975000,72.205741
...
-44.975000,170.975000,93.254147

i.e. latitude, longitude, and an attribute in the third column.

I import it into a latlong location using v.in.ascii and then try and
project it into a location that uses the New Zealand Mapping Grid
projection, but I get the following output:

------------
> v.proj input=lhumile_ddays location=latlong

Input Projection Parameters: +proj=latlong +a=6378388 +rf=297 +no_defs
+towgs84=59.47,-5.04,187.44,0.47,-0.1,1.024,-4.5993
Input Unit Factor: 1

Output Projection Parameters: +proj=nzmg +lat_0=-41.0000000000
+lon_0=173.0000000000 +x_0=2510000.0000000000 +y_0=6023150.0000000000

+towgs84=59.47,-5.04,187.44,0.47,-0.1,1.024,-4.5993
Output Unit Factor: 1

Creating vector file...
pj_transform() failed
cause: latitude or longitude exceeded limits
Error in pj_do_transform

------------

None of the latitude/longitude values appear to be out of range. Is
there anyway to get more information? Or does anyone else have a clue
on how to fix this?

Thanks for your time.
