Directions:
The cache (accuracy 10 m; elevation 665 m) is hidden in a 10 litre white plastic bucket within prickly scrub about 250 m north of the summit of Flagstaff Hill (S 45°49.958' E 170°27.979' Elevation 668 m). See the hints for more detail.
To get there you have three options (in increasing order of difficulty):
1. Follow the Flagstaff Whare Flat Road from Three Mile Hill Road and park at the Bull Ring (S 45°50.066' E 170°27.094'; elevation 511 m). Now walk up the moderately steep gravel track for about 30 minutes until you reach the top of the hill (a 150 m climb; don't forget to stop and admire the panoramic view of the city and the Taieri plain (see the photos below)).
2. Park on Booth Road (S 45°50.459' E 170°29.605'; elevation 183 m). Walk for about 1 hour and 30 minutes, first up the remainder of Booth Road and then up a relentlessly steep gravel track to the top of Flagstaff Hill (a 500 m climb).
3. Park at the end of the seal on Spiers Road (S 45°51.142' E 170°27.932'; elevation 305 m). Next follow the gravel road up to a sign marking the beginning of the track. Follow the white or silver markers through the scrub for about 1 hour and 30 minutes (a 350 m climb; parts of the route are steep and muddy; bring a map and compass; you will meet a gravel track (at S 45°50.010' E 170°27.805'; elevation 647 m), now turn right and follow the track for 250 m to the top of Flagstaff Hill.
Free Hint: It is easiest approach the cache from the south-west.
