The cache (Accuracy 20 m Elevation 80 m) is buried (no digging required) in a 3 litre rectangular translucent plastic snap lock container, about 200 m south of the upper Botanical Gardens car park (S 45°51.511' E 170°31.320' Elevation 88 m) and 450 m south-east of the lower car park (S 45°51.463' E 170°31.063 Elevation 32 m).
I recommend using the larger lower car park (off Cumberland Street). It's a pleasant walk up through the Botanical Gardens to the cache. However, you may get to the upper car park from either Dundas Street or Opoho Road via Lovelock Avenue.
Free Hint: There are two crossed sticks on top of the cache. Note that, it will be very difficult to find if the markers have been removed or disturbed. You may have difficulty obtaining an accurate position fix in the dense bush.
