[TheList] Grid Reference on MED website

Fri Aug 20 20:35:43 AEST 2010

Hi Chris,

It's the new Topographical Map Grid Reference system, called NZ Topo 50, 
the old system from 1949 was called NZMS 260. MED only recently 
converted to the new Topo 50 system from the much older 260.

The new system aligns much closer to the WGS84 International system used 
by GPS's. The older system was out by up to about 200m.

There is an online converter here:

Regards,

Neill.
