I thought it was about time Tauranga had a Wherigo cache so why not give it a go?
This cartridge was written using the Urwigo toolkit and field-tested on a Samsung smartphone using the WhereYouGo app. I can't vouch for any other platforms but I've deliberately made the game mechanics simple so fingers crossed, eh?

An art tour of Tauranga
Follow the hints and collect the clues to find the location of the secret package!
The Wherigo takes around an hour or so, depending on how well you know Tauranga CBD. Make sure you have a full charge on your smartphone battery! Google is your friend for some of the clues and Google maps may be helpful if you don't know Tauranga too well.
You can download the Wherigo cartridge here
If you haven't played a Wherigo before, it might be useful to have a go at GC7NHZ9 Turning Over a New Leaf (BOP) first as an introduction to the mechanics of the game.

You can validate your puzzle solution with certitude.
Don't forget the last artwork for the hint...
Have Fun!!!
