We use NZ Post for getting our cards out to everyone - either by courier or by mailbox. I have to say their service is amazing and our local postie has definitely become a familiar face around our home / studio / home office! We've also just learnt that they are now 100% Carbon Neutral when it comes to person to person sending which is what we do. So every time we send out a package of cards any emissions created which cannot be avoided are now offset with carbon credits from local native forestry and international gold standard projects. Go NZ Post! You share values which are very close to our heart and definitely what we aspire to.
