New Zealand lunar eclipse: Where and how to see it

Some stargazers in New Zealand will be treated to a rare sight on Wednesday morning - a partial lunar eclipse.

The first signs will become visible at 6:43am on Wednesday as the shadow of the earth starts touching the moon's face, creating a penumbral lunar eclipse.

"The very earliest stages of this eclipse are visible from New Zealand, especially the South Island," the Royal Astronomical Society of New Zealand (RASNZ) says on its website.

As the moon will be close to the horizon, it's best to make sure you have free sight to west-southwest.

"We recommend going to a high point or finding an unobstructed area with free sight to west-southwest for the best view of the eclipse," eclipse tracking website timeanddate.com says.

"A penumbral lunar eclipse can be a bit hard to see as the shadowed part is only a little bit fainter than the rest of the moon."

The partial eclipse itself will start at 8:01am, but only be visible for the lowest parts of the South Island.

"During this partial lunar eclipse, the Earth's shadow covers only parts of the moon, as seen from Invercargill," timeanddate.com says.

If you want to see the eclipse in its full glory, you'll have to travel overseas.

"Australia will see rather more of the eclipse but even there essentially only Western Australia will see the maximum eclipse," RASNZ says.

"The best places for viewing the entire eclipse will be South Africa and Madagascar."
