Im going to be arriving in Christchurch and planning on going backpacking for a week or 2, only problem is I have a fair a amount of valuables on me (laptop, headphones etc) and want to avoid damaging these so I was thinking about leaving them at a self storage company. Has anybody done this or could recommend a good company?

I was going to just take out travel insurance but on looking at the small print its not worth the paper its printed on :/
