The Māori lunar calendar, or Maramataka, is used to determine the best time for many activities, including planting, harvesting, and fishing. The Maramataka is based on the phases of the moon, and the appearance of the full moon at different times of the year signals different activities, for example:

Pipiri (June/July): The full moon in this month signals the time to plant kumara (sweet potato).

Mahuru (April/May): The full moon in this month marks the end of the harvesting season.

Rākaunui: The full moon, when eel fishing is not productive because the bright moon light makes it hard for eels to hunt.
