Having options to load the post code directly or having all dual area codes for a town/suburb available to choose from i.e - Te Puke has 2 post codes 3119 & 3182 depending on if you are rural or urban areas
Papamoa has multiple (5) post codes - 3118, 3175, 3183, 3189 & 3187 (new papamoa east suburb). Not all are available in REX and clients are not happy when the wrong post code is showing online.
