In Zelda Tears of the Kingdom, there are six bring-peace quests, and Neculada is the second after the Bring Peace to the Hyrule quest is first begun. Similar to the previous, Link has to help Hoz and his crew to defeat some monsters. Let’s break it down, though, and explain how to complete Bring Peace to Necluda quest in Zelda Tears of the Kingdom.
Bring Peace to Necluda Quest Walkthrough in Zelda Tears of the Kingdom

You can complete Bring Peace to Necluda in the Zelda Tears of the Kingdom by defeating all monster forces. Once you defeat monster forces at Hyrule, Hoz says they are heading to Fort Hateno to fight more monsters. You need to go there and speak with Hoz to start this quest. Here are the steps you need to follow.
1. Speak to Hoz to start the quest.
You will meet him at the northeast of Blatchery Plain in east Necluda. The exact location of the quest is shown on the above map. Once you speak to Hoz, he will ask you to join the battle, and the quest will start.
2. Go to the monster stronghold and defeat them.
The monster stronghold is nearby, so the crew will soon attack the monsters. Unfortunately, there are more monsters in there than in Hyrule. But use Flower Bombs and weapons such as Balck Boko Blade, and they will eventually be defeated.
3. Speak with Hoz after killing the monsters.
Once you have defeated all monster forces, you must return to Hoz, who will thank you for your help. He will also give you a reward of 100 rupees as the reward. This will complete the Bring Peace to Necluda quest in Zelda Tears of the Kingdom. Also, if this is the last quest of bring peace questline, you will receive Monster-Control-Crew Fabric for completing the questline.
However, the other four quests are not given by Hoz. Instead, you have to meet the other monster-control crew leaders to obtain those quests. This quest is relatively easy to complete since you only need to defeat monsters and talk to Hoz. After completing it, you can continue with the other four quests. If you still need visual guidance, the below video from Kawffee will help.
