Mokoia Island / Te Motu-tapu-a-Tinirau
Mokoia Island is tapu (sacred) largely because of the presence of Matuatonga which is still there. Kūmara grow well on Mokoia, which is attributed to the great powers of Matuatonga. Each year before planting began the tohunga (wise scholar) took their seed-kūmara to the island and touched Matuatonga, thereby gaining its mana (power).
Te taiao (the environment) on Mokoia Island is ideal for growing kūmara. It is East facing providing all day sun. The island is a shelter-belt from the harsh westerlies. The thermal heat provided for growing kūmara all year round. The volcanic soil, is an ideal medium for the kūmara while at the lake’s edge the sand would have been great for growing tipu and of course the lake had pristine waters unlike today.
Whakataukī / Māori proverb
Ko te wai te toto o te whenua
Ko te whenua te toto o te tangata
As water is the blood of the land
So the land is the blood of humanity
Te Kete Rokiroki a Whakaotirangi
The secure Basket of Whakaotirangi
This refers to our ancestress tupuna, Whakaotirangi. Tasked with securing the kumara as Te Arawa waka journeyed to Aotearoa around the year 1300AD. On arrival at Maketu, Whakaotirangi disembarked and planted the first tipu putting in place the tradition of growing kūmara here in the Bay of Plenty and Rotorua.
Kāore to kūmara he kōrero mō tōna ake reka
The kūmara never speaks of its own sweetness
Maramataka / Māori Moon Calendar

Kai Rotorua uses the Maramataka as a tool for the following purposes:
- Growing and harvesting kumara.
- The best days for planting.
- Planning ahead for hui, workshops, seminars, mahi or an event.
We also use the Maramataka to respond to and understand days set outside our control. i.e. when a hui/event is set by a third party. The Maramataka is an instrument that measures high, medium or low energy levels allowing us to respond accordingly.
Kumara seed are planted in tapapa (seed beds) at Ohinemutu in a thermal environment. It is about 2 months before the tipu (seedlings) appear ready to harvest at which time they are placed in water to harden off before planting either at the end of October or early in November after the last frost.
Preparation of the maara kumara (plantation) is completed in the lead up to September which begins with ‘broadcasting’ green cover crops, oats and blue lupin seed. At about 1m the oats and lupin are turned back into the soil before applying organic fertiliser. 50m rows are prepared before the next rainfall then polythene is laid over each row. This provides a number of advantages. It locks in the moisture after the rain. It creates an artificial heated environment for the kumara, and is a great weed suppressant. Another great advantage is we have never had to apply water. Finally, weed matting is placed between the rows providing another benefit being the kumara vines cannot take root ensuring the parent isn’t competing for nutrients.
