Sun rise and set times for other parts of New Zealand
The times of Sun rise and set for other places in New Zealand can mostly be estimated within about 5 minutes from the times in the tables. Note that for places with the same latitude, a difference of 1° in longitude makes a difference of 4 minutes. Times are earlier for places to the east and later for places to the west. Thus Sun rise and set times for places on the west coast are mostly about 12 to 15 minutes later than those for places on the east coast.
In the North Island, Auckland and Wellington are virtually the same longitude, so for places like Hamilton, Taumarunui, Wanganui and Palmerston North, between them, times can be determined by proportion.
Also note that in midsummer, December and January, times of Sun rise for all places on the east coast of New Zealand are almost the same. This is true from East Cape, north of Gisborne in the North Island to Dunedin and Stewart Island in the South Island and includes Wellington. The same applies to the time of Sun set in winter, June and July.
Near the equinoxes, in March and September, latitude is unimportant, the times of Sun rise and set depend on longitude as explained above. That is, places at the same longitude have similar times of sunrise and sunset, whatever their latitude.
In summer for places with the same longitude, sunrise is earlier and sunset later the further south one goes, ie the hours of daylight are longer. The reverse is true in winter, hours of daylight are less in the south, that is the sun rises later and sets earlier in the south compared to the north, again for places at the same longitude.
