Where can I find spare parts for my tablet

The little pins where I plug my charger into my tablet are damaged so I dismantled it because my tablet wasn't charging anymore and I noticed that the little pins (whatever they're called) were not going into the middle part of the charger connection when I went to charge it so when I opened it up very carefully I disconnected the charger connector and have been looking for the same part to replace it in NZ but no one can help me I hope you or someone can help me please or steer me in the right direction cos most people just say ' buy a new one' but I don't want to because I believe it's fixable thanks Sina
