Our resident geologist, Tanguy Racine, sates our apatite for sedimentary reasoning, with this deposition on New Zealand's faults, marbelous formations and other boulder topics.

We turn out to be hazardous material in the eyes of the New Zealand border control. It seems foreign dirt is not something they want on their soil. Unfortunately our kit is mostly comprised of dirt.

I spent Sunday evening modifying a Makita drill to use an external battery. The drill is slightly different from the one we already had, and after a bit of experimental soldering, it seems to be working fine. I'm posting this guide in case it helps anyone else wanting to modify one of these drills.

A guest post from Jarvist Frost, veteran caver and inveterate tinkerer on the new Lithium Ion batteries we'll be taking to New Zealand for our drills.

Tanguy, Rhys and Jack went on an Expedition First Aid Course run by Marlin Training, where we learnt advanced techniques such as injections, suturing and using oxygen masks.

The first NZ expo specific trip! A fantastic first aid training weekend complete with in-cave simulations in Goatschurch and a tourist trip to GB Cavern on Sunday.
