Wellington is the capital city of New Zealand. This graticule is not ideal for geohashing as most of the graticule lies in the ocean, and that which does not is divided evenly between the North Island, the South Island, and inaccessible land in the Marlborough Sounds.
Also, as for all New Zealand graticules, the Dow Jones does not open for any day until it is 1:30am the next day in New Zealand. Weekend meetups are still possible, however.
A quick survey: out of all the Satrudays so far in the year (up to 17/05/08), 14 were in the sea, three were in the North Island, two were in the Marlborough Sounds, and one was in Lake Grassmere in the South Island. The meeting for 23/03/08 would have been in Central Wellington.
