The best spot to view Thursday's rare blue supermoon is in the eastern parts of both of Aotearoa's main islands, according to MetService.
The weather forecaster said eastern Te Ika a Māui/the North Island and eastern Te Waipounamu/the South Island are the most likely places to have clear skies.
Tāmaki Makaurau/Auckland, Waikato, and Te Moana a Toi/Bay of Plenty should be in luck, with clear skies forecast.
"Supermoons look about 8 percent bigger and about 16 percent brighter than an average full moon," Stardome astronomer Rob Davison said.
The sky in Te Tai Tokerau/Northland will clear late in the day for skywatchers.
In Tairāwhiti/Gisborne and Te Whanganui a Tara/Wellington, cloud could disrupt moon gazers.
Meanwhile, Te Matau a Māui/Hawke's Bay and Wairarapa should be in the clear.
Western and southern parts of Te Waipounamu/the South Island will be in the firing line for some showers and cloud cover.
With a high-pressure system dominating much of Aotearoa, the clear skies for most are likely to bring very chilly temperatures - so wrap up warm.
The next blue supermoon will be in 2032.
