I am looking at buying something off amazon as follows...

Order Summary
Items: NZD 485.65
Shipping & handling: NZD 21.84
Total before tax: NZD 507.49
Estimated tax to be collected: NZD 0.00
Import Fees Deposit NZD 111.19

I was wondering, would this cover GST?  

I went into the NZ customs fee calculator and on 507.49 it calculates...

Estimation Summary

Item Duty
Computers
Value: 507.00 NZD
Duty: 0.00 NZD
GST: 76.05 NZD
76.05 NZD
GST on freight 0.00 NZD
Total 76.05 NZD
Entry fees* 49.24 NZD
Amount due 125.29 NZD

NZ customs is $125.29 but amazon is only $111.  Close but not the same so I am unsure. 

Anyone know? I may need to call nz customs or amazon chat to find out.
