Māui and the giant fish
Fact 1: Māui has a Jewbone that his ancester Murirangawhenua gave him and he used it as a fishing hook.
Fact 2: Māui made a fishing line out of flax one night when he was alone and recited an old karakia to give his fishing line strength.
Fact 3: Māui brothers wouldn't give him any bait, so he punched himself in the the nose to make it bleed and used the blood for bait.
Other stories I have heard about Māui is:
Māui and the sun: The sun is not giving light for a long time because the sun just wants to sleep. The people working don't get time to do all their work. Māui trys to stop the sun but now the sun is going for so so long so no one can go to sleep, but luckly for us Maui has gone up again and stopped him once more and made it all fear, so now the sun is up for 12 hour's and down for 12 hour's.
