Several star signs will become "crazier than usual" as the blood supermoon illuminates New Zealand skies on Wednesday evening, an astrologist claims.
The rare spectacle occurs when a blood moon, also known as a total lunar eclipse, occurs at the same time as a supermoon.
It was last seen in New Zealand about 40 years ago, but will be visible for a short time on Wednesday night, from 11:11pm to 11:25pm.
But Australia's intuitive astrologer and spiritual advisor Rose Smith is warning the phenomenon also occurs at the same time Mercury is in retrograde.

She told news.com.au the three events combined will create a "tremendous amount of emotion" for every star sign.
"Full moons ordinarily can bring out the 'crazy' in people, but we can expect people doing crazier things than usual - and this can be attributed to pent-up emotional tension," she told the news outlet.
"People should be trying to release this tension around the super blood moon in healthy ways, sitting with their feelings and endeavouring not to deny them. Especially women, generally speaking, traditionally we hold in emotion and make excuses for other people."
However, the three fire signs will be particularly affected.
"As the total lunar eclipse and super blood moon are in Sagittarius, it could be a particularly emotional time for fire signs Aries, Leo and Sagittarius," Smith said.
"Fire signs are going to be more affected than the rest of us, but we will all be affected in some way."
She said it is also likely to affect the relationships between many couples, with issues including behaviours, arguments and past traumas potentially coming to the forefront.
"There's going to be a great push for Sagittarians and other fire signs to get rid of toxic situations and relationships," she told news.com.au.
"A lot of relationships are going to break up in this period - all signs, everybody will be affected - but fire signs will bear the brunt of it."
For those Kiwis looking to catch a glimpse of the blood supermoon, weather forecasters have told Newshub conditions are looking good.
Based on NIWA's models, the best places to view the super blood moon are: Southland, Otago, West Coast, Canterbury, Tasman, Nelson, Marlborough, Wellington, Manawatu-Whanganui, Taranaki, Waikato and Auckland.
Meteorologist Ben Noll said there will be some scattered cloud for Fiordland, Northland, and Bay of Plenty, but stargazers shouldn't be discouraged because there may be enough breaks in the cloud to spot the moon.
