The 'D' Puzzle Challenge (Canterbury) Mystery Cache

Love 'em or hate 'em. Here's another challenge.

I love numbers and box ticking if you do too then read on, if not this won't be for you. 

I love puzzles too, to get the for this one you need to find 9 caches, simple. The requirements are as follows:

1. Each of the nine caches need to be Mystery caches with the lovely blue ?.
2. Each of the puzzles need to be in ascending order along the Difficulty range from D1-D5.
3. Each of the qualifying caches need to be from different cache owners.
4. Challenge caches do not qualify for this one, they need to be puzzles.

All caches past, present and future count for this challenge. I know heaps of the puzzle solvers out there have already qualified.

1. GC4K8PY, South Hagley Park, Rincewind3, 1
2. GC2DDCT, A Prime Location (Otago), katie w, 1.5
