Hi everyone and my apologies in advance if this is posted somewhere but I’m unable to locate it.

I’ve just returned to NZ, a MacBook Pro 13in I had instorage is not charging and needs a new battery. It’s an older unit at late 2011, model A1278. Replacing a battery seems easy enough but for the life of me I can’t find a supplier that will sell me the battery and associated tools required. Amazon has them but won’t ship here, obviously I’m missing something 🤷🏻‍♀️ Any advice or direction gratefully received! I’m in Christchurch.
