Another barrier cache on SH 1, this time between Koromiko and Tuamarina. This one is not a BBC (Bridge Barrier Cache), but it probably is a BBC (Boring Barrier Cache). It is best to target this one while travelling south. There is plenty of space to pull over and stop at GZ. Check the nearby milking shed for activity and grafitti, it is probably not a good idea to retrieve the cache while milking is taking place.
SAFETY WARNING This is a busy State Highway so please be mindful of the children who are caching with you. This is the reason my BBC Series are micros and have no swag, swaps or trades and have a 'Not Suitable for Children' attribute.
UPDATE: 30 January 2020 Unfortunately the structure (milking shed) in the distance with the graffiti on it that advises what Vince loves has collapsed and you can no longer see what Vince loves, but if you are interested, there is a photo that has been uploaded to the gallery that shows it clearly. I have also included it as the hint.
