There's also a hidden entrance down by the law building on Waterloo Quadrant. Sort of looks like a water duct but it connects up to the Albert park ones
Great job Luke! You clearly have worked on your presenter voice. I did a bit of research on these tunnels a we while back. There are also some tunnels in the former Auckland College of Education campus. There are also a few gun emplacements around mission bay and on the islands around Auckland. Have you checked out a youtuber called Tom Scott? You might get some inspiration from him.
Draco Venit hey thanks for the comments. yup my videos are entirely inspired by Tom Scott. didn't know about the tunnels at Auckland college I'll have to check that out. feel free to check out my other videos in the meantime this is one of my earliest videos. cheers
