This is my (first) contribution to the CCCCA series, started by PaoloB72.
Following on from the CCA (Chorus Cabinet Art) series in Marlborough, administered by Kiwimykl, and the similar CCA series on the West Coast by Holymu and Hazedarus, here is the CCCCA (Christchurch City Chorus Cabinet Art) series, started to highlight the local artistic talent that Chorus (and sometimes other utility providers) have commissioned to brighten up their otherwise boring public utility boxes. The majority of the hides will be Multi caches but there may be the occasional Mystery. Tradionals are unlikely as PUBs are out of bounds for placing caches on, under, or nearby. Like the other series, others are welcome to join in as long as the numbering system continues, PaoloB72 will endeavour to keep a good list.
This colourful artwork in Harris Cres is by Ruey Yoong.

Count the number of butterflies on the LEFT side, the FRONT and the RIGHT side and take note of the date on the front at the lower right.
The final is a short walk away at S 43° 29.ABC E 172° 35.DEF
where
A = FRONT + RIGHT
B = LEFT - RIGHT
C = LEFT + FRONT
D = Last year of date
E = RIGHT
F = Last year of date - first year of date
Checksum A:F = 36
Cache is a small pill bottle inside a slightly larger one.
