Just to clarify, after reading a bunch of posts and doing this myself. I had ran to Kaniz's spawn point around 17 times, after getting the emote.
I can confirm that he is indeed on a 3 day timer. From the time a guildy killed him, I went there at least 5 times per day every few hours over the course of 3 days, and he finally popped on the third day.
I would also recommend taking a certain path to him. There's paths that have a TON of trash, and 1 path that has about 3-4 mobs you may have to kill. For those, if you don't want to fight them, you can Spirit of Wolf yourself and run through since they're low level.
Here's a map I took and made a path in green as to where you should go. The red dot is where he spawns, for more clarification. He doesn't spawn up the stairs.

The above link is for the map.
Hope this helps.
