Donovans
Located near Wainui, Canterbury, it is about 1 hour and 20 minutes drive from Christchurch on the way to Akaroa.
Very few clues apart from that. When you get to the Llama and Lodging, continute to drive up the left until you hit the end of the road at a gate. You are now within 10m of the cache. It is on this side of the fence. You do not need to go through the gate (which is private property) unless you accept the invitation in the cache. ;)
