Fishing:

Maori fishermen would specially name rocks, banks and fishing grounds where they would fish. Some of these were several kilometers out in the sea.
Fishermen would use landmarks to mark where their favourite fishing spots were. To find one of their fishing spots they would line up a cliff with a mountain, or a river with a peninsula.
Most fishing grounds were protected by the area’s tribe, and were passed down from generation to generation. These fishing areas were protected through jealousy, so that other tribe’s fishermnn could not fish from these spots.
It was quite common to see rows of stakes around fishing grounds - especially lakes and shoal- infested waters.

Gardening:

Before Maori started planting, they cleared and cut an area of forest, and burned the waste. Then they prepared the soil by scattering the ash from the burnt trees over the garden, and adding a composite of sand and gravel to heavy and/or clay soils. The terrain wasn't normally dug over fully.  As an alternative, they fashioned the terrain into minute heaps for kumara, or they dug into the ground to create low pits for taro or gourd.
The gardeners used this garden over a period of 2–6 years and then they abandoned it and let it grow over for numerous years, and due to the fast-growing properties of the native forest, it was virtually invisible by the time they returned.
By digging ditches around their gardens, Maori may have been setting apart borders and/or draining the excess water away. To keep out prowling pūkeko (swamp hens), they set up reed or mānuka-brush fencing to shield their crops. A few abandoned garden sites have stones in long rows, perhaps as a barrier, or as a form of marking confines.

Hunting:

The Maori used specific tracking methods to hunt the moa and wild pigs.
They set traps to catch birds. They would use bait and other methods to lure the birds to their traps.
The weapons they used were spears (taiaha) and clubs (patu, kotiate) and more.

Carving:

The Maori carvers would ask Tane Mahuta for permission to cut down the trees from his forest so they could use the wood for carving.
The Maori use carving on most wooden surfaces, from fishing hooks they use to catch fish, to the wharenui where they sleep.
Maori carvers would use several tools such as chisels (whao), pipi shells and sharp stones.
