ORA_NZ_BN	New Zealand Business Number	13	Numeric Characters Only	Yes, 13th Digit (Last Digit)	It is a 3-step process as stated below: Multiply value of each position left to right all 12 digits by 1,3,1,3,1,3,1,3,1,3,1,3. Add the resulting 12 products and arrive at a sum. Subtract the sum from nearest equal or higher multiple of ten = Check Digit.

ORA_NZ_GST	New Zealand Goods and Services Tax Registration Number	8 or 9	Numeric Characters Only	Yes, last digit	If the IRD number is < 10-000-000 or > 150-000-000 then the number is invalid. (This step ensures that the IRD number is in the al-ready issued range, or is in the range expected to be issued in the next 10 years.) Check Digit Validation: Remove the trailing check digit. If the resulting number is seven digits long, pad to eight digits by adding a leading zero. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 3, 2, 7, 6, 5, 4, 3, 2. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 3, 2, 7, 6, 5, 4, 3, 2. Divide the sum by 11. If the remainder is 0 then the calculated check digit is 0. If the remainder is not 0 then subtract the remainder from 11, giving the calculated check digit. If the calculated check digit is in the range 0 to 9, then that digit is the check digit. If the calculated check digit is 10,then follow the below steps. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6. Multiply each digit with a 'weighting factor' as per its position.

It is a 3-step process as stated below:

Multiply value of each position left to right all 12 digits by 1,3,1,3,1,3,1,3,1,3,1,3.
Add the resulting 12 products and arrive at a sum.
Subtract the sum from nearest equal or higher multiple of ten = Check Digit.

New Zealand Goods and Services Tax Registration Number

8 or 9

Numeric Characters Only

Yes, last digit

If the IRD number is < 10-000-000 or > 150-000-000 then the number is invalid. (This step ensures that the IRD number is in the al-ready issued range, or is in the range expected to be issued in the next 10 years.)
Check Digit Validation:
1. Remove the trailing check digit.
2. If the resulting number is seven digits long, pad to eight digits by adding a leading zero.
3. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 3, 2, 7, 6, 5, 4, 3, 2.
4. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 3, 2, 7, 6, 5, 4, 3, 2.
5. Divide the sum by 11.
  - If the remainder is 0 then the calculated check digit is 0.
  - If the remainder is not 0 then subtract the remainder from 11, giving the calculated check digit.
    1. If the calculated check digit is in the range 0 to 9, then that digit is the check digit.
    2. If the calculated check digit is 10,then follow the below steps.
    1. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
    2. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
    3. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
    - Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
    - Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
    1. Multiply each digit with a 'weighting factor' as per its position. Coefficient: 7, 4, 3, 2, 5, 2, 7, 6.
