To read Māori moon phases, you must consult the Maramataka, identifying the specific night within the 30-day lunar cycle. This involves observing the moon’s shape and position to determine the current phase—such as Whiro (new moon) or Rakaunui (full moon)—and interpreting the associated energy levels to guide activities like fishing, gardening, and self-reflection.
The Ancestral Origins: History of Māori Astronomy
To truly understand how to read moon phases in the Māori tradition, one must first appreciate the depth of Tātai Arorangi (Māori astronomy). For centuries before the arrival of Europeans, Māori were master navigators and observers of the cosmos. The sky was not merely a backdrop but a vast, intricate map and a calendar that dictated survival.
The ancestors arrived in Aotearoa (New Zealand) using the stars, the sun, and the moon to guide their waka (canoes) across the vast Pacific Ocean. Upon settling, this celestial knowledge evolved from navigational necessity to a sophisticated system of timekeeping and resource management. Unlike the solar Gregorian calendar used in the West, which is somewhat detached from the immediate environment, the Māori system is inextricably linked to the natural world.
Tohunga kōkōrangi (expert astronomers) would spend years memorizing the movements of celestial bodies. They understood that the moon (Marama) exerted a gravitational pull not just on the tides, but on the water within plants, animals, and humans. This historical context is vital; when you learn how to read moon phases Māori style, you are not just reading a calendar—you are accessing an ancestral data set compiled over a thousand years of observation.

What is the Maramataka?
The Maramataka is the traditional Māori lunar calendar. The word literally translates to “the moon turning” (Marama = Moon, Taka = to turn or rotate). However, describing it simply as a “calendar” is a reduction of its function. It is a predictive environmental system.
While the Gregorian calendar marks time in a linear fashion (Monday followed by Tuesday), the Maramataka marks time through cycles of energy. It divides the lunar month into distinct nights—usually 30, though this varies slightly between Iwi (tribes)—each with a specific name and a specific set of characteristics. These characteristics tell you whether it is a good day to fish, a good day to plant kumara, a day to hold high-level discussions, or a day to rest.
The cycle restarts with the New Moon (Whiro). Understanding the Maramataka requires a shift in mindset from “What time is it?” to “What is the energy of the environment right now?” This alignment allows for a more harmonious existence with the natural rhythms of the earth and sky.
Identifying the 30 Nights of the Moon
Learning how to read moon phases Māori involves memorizing the visual cues of the moon and associating them with their specific names. The cycle is generally split into phases that mirror the waxing and waning of the moon. Below is a breakdown of the critical phases and how to identify them.
The Whiro Phase (New Moon)
The cycle begins with Whiro. Visually, this is when the moon is invisible or a mere sliver of darkness. In Te Ao Māori, Whiro is associated with darkness and low energy. It is often considered an unfavorable time for fishing or planting, as nature is in a state of rest. However, for modern astronomers and aurora hunters, Whiro is the ideal time to observe the night sky because the absence of moonlight makes the stars and the Aurora Australis pop with intensity.
The Waxing Moon (Ngā Tamatea)
As the moon begins to grow (wax), we enter the nights of Tirea, Hoata, and Oue. The crescent becomes visible. Following these are the Tamatea nights (Tamatea-a-ngana, Tamatea-a-hotu, etc.). Visually, the moon is approaching the half-moon stage. The weather during the Tamatea phase is often unpredictable and volatile. The ocean can be rough, making it a time for caution.
The Full Moon (Te Rākaunui)
The most recognizable phase is the full moon, known as Rakaunui (or Rākau-nui). At this stage, the moon is a complete, bright disc. This represents high energy. Visually, it dominates the night sky. In terms of productivity, this is often a time of abundance. Crops planted now are said to grow bountifully, and the sap in trees is running high.

The Waning Moon (Tangaroa)
After the full moon, the light begins to recede. We enter the Tangaroa phases (Tangaroa-a-mua, Tangaroa-a-roto, Tangaroa-kiokio). Visually, the moon is losing its perfect roundness but remains bright. Tangaroa is the god of the sea, and consequently, these days are considered the premier times for fishing. The tides are often favorable, and fish activity is high.
The Darkening Phase (Korekore)
As the moon shrinks back toward a sliver, we enter the Korekore nights. “Kore” implies “nothing” or “nil.” Visually, the moon is a waning crescent, appearing later in the night or early morning. These are generally low-productivity days for food gathering (fishing and planting yields are poor) but are excellent for planning, reviewing, and mental work.
High Energy vs. Low Energy Days
The core utility of the Maramataka lies in distinguishing between high and low energy days. When you ask “how to read moon phases Māori,” you are essentially asking how to optimize your schedule based on environmental energy.
High Energy Days (Mauri Ora)
High energy days are characterized by high productivity in the natural world. The gravitational pull is strong, stimulating activity in marine life and fluid movement in plants.
- Key Phases: Rakaunui (Full Moon), Tangaroa phases.
- Activities:
- Fishing: The Tangaroa nights are legendary for fishing success. Eels and crayfish are active.
- Planting: Rakaunui is ideal for planting root vegetables as the energy encourages fullness.
- Action: Launching new projects, hosting events, and physical exertion.

Low Energy Days (Mauri Noho)
Low energy days are not “bad” days; they are simply days for different activities. Nature withdraws to recharge, and humans are encouraged to do the same.
- Key Phases: Whiro (New Moon), Korekore phases.
- Activities:
- Rest: Avoid strenuous physical labor if possible.
- Planning: The Korekore nights are perfect for strategy meetings, learning, and wananga (educational forums).
- Maintenance: Repairing nets, weeding gardens (as opposed to planting), and cleaning.
Te Ao Māori Worldview and Environmental Connection
Reading the moon phases is a gateway into the broader Te Ao Māori (The Māori Worldview). It reinforces the concept of Whakapapa (genealogy), connecting humans to the cosmos. In this worldview, the moon is not an inanimate rock; it is an ancestor affecting the Mauri (life force) of the world.
Connecting with Atua
Different phases are linked to different Atua (Gods/Guardians). For instance, the Tangaroa nights connect to the guardian of the ocean. By fishing on these nights, you are aligning with the rhythm of Tangaroa. Conversely, during the Tamatea phases, associated with unpredictable weather (Tāwhirimātea), one learns respect for the elements by exercising caution.
This connection fosters sustainability. If the Maramataka says it is a bad day for fishing (Korekore), and you respect that, you are naturally practicing resource conservation, allowing fish stocks to replenish.

Applying the Maramataka Today
While rooted in history, the Maramataka is experiencing a resurgence in modern New Zealand society. It is being used in sectors ranging from mental health to agriculture and tourism.
For Gardeners and Farmers
Permaculture enthusiasts and organic farmers are increasingly turning to the Maramataka to increase yields without chemicals. Planting by the moon ensures that seeds are sown when the water table is optimal for germination.
For Mental Health and Wellbeing
Understanding the energy of the days helps in managing personal wellbeing. Recognizing that a “low energy” feeling might coincide with a Whiro or Korekore moon phase can validate one’s need for rest, reducing the guilt associated with taking a break in our hyper-productive modern society.
For Astronomy and Tourism
For those in the NZ Astronomy and Aurora Tourism niche, the Maramataka is an essential tool. Knowing that Whiro (New Moon) provides the darkest skies allows tour operators to plan the best aurora hunting experiences. Conversely, knowing when Rakaunui (Full Moon) rises allows for “Moon Walk” experiences where the landscape is illuminated naturally.
Frequently Asked Questions
What is the Māori word for moon phases?
The general term for the moon is “Marama.” The system of lunar phases is called “Maramataka.” The specific nights (phases) are often referred to as “Ngā pō o te marama” (The nights of the moon).
How many phases of the moon are there in Māori?
Most Iwi (tribes) recognize 30 distinct nights (phases) in the lunar cycle. However, because the lunar month is approximately 29.5 days, some months may omit a night or merge phases depending on the specific tribal dialect and observation.
What is the best moon phase for fishing Māori?
The best phases for fishing are generally the Tangaroa nights (Tangaroa-a-mua, Tangaroa-a-roto, Tangaroa-kiokio), which occur after the full moon. These times are associated with productive ocean activity and favorable tides.
What is the Maramataka calendar used for?
The Maramataka is used to guide daily activities based on environmental energy levels. It determines the best times for planting, fishing, eel gathering, resting, holding meetings, and conducting rituals to ensure success and safety.
When does the Māori lunar month start?
The Māori lunar month typically starts with Whiro (the New Moon). The New Year (Matariki or Puanga) begins with the first new moon following the rising of the Matariki star cluster or the star Puanga (Rigel), usually in mid-winter.
What is the difference between Rakaunui and Whiro?
Rakaunui is the Full Moon, representing high energy, abundance, and visibility—ideal for action and planting. Whiro is the New Moon, representing darkness, low energy, and rest—ideal for planning and observing the stars.
