Aus Post website says parcel pending

All services we offer from Aus Post are a joint venture between NZ Post and Australia Post, which means both carriers track your parcel at different journey points. 

• NZ Post tracks your parcel from our warehouse to customs in Australia 
• Aus Post tracks your parcel from customs to your door. 

Our Mix Wizard tracking page merges notifications from both carriers into one single feed. You will start to see notifications on the Aus Post website as soon as your parcel clears through customs, as it will be treated as any other domestic parcel in their network.
