The first entries are unrelated.

This is a memory dump and could be unrelated (or maybe not).
> TopMemoryContext: 268428304 total in 26 blocks; 5528 free (22 chunks); 268422776 used
> Local Buffer Lookup Table: 2088960 total in 8 blocks; 501416 free (22 chunks); 1587544 used
[snip some more]
The real problem is here:
> 2010-08-17 19:19:32 NZSTLOG: server process (PID 6684) exited with exit code 128
> 2010-08-17 19:19:32 NZSTLOG: terminating any other active server processes
The rest is just noise about other processes being killed by postgres to
reset memory to a known-good state.
What you need to investigate is what caused that process to exit with
code 128.
PS: it'd be a good idea to append some whitespace to log_line_prefix, to
ensure that timezone NZST is separate from the "LOG" tag.
