Checks a string against the New Zealand Ministry of Health NHI Validation Routine. Supports the old and new NHI number formats specified in HISO 10046:2023.

Getting Started

npm install nhi-validator
import {validateNHI} from 'nhi-validator'

validateNHI('WLD9413') // => true
validateNHI('zsc21tn') // => true
validateNHI('zzZ0044') // => false
validateNHI('ZZZ00AA') // => false

Checks are case-insensitive.

Excluding Testcases

NHI numbers that begin with Z are reserved for testing. If you wish to exclude these values, you will need to manually check for a Z prefix:

import {validateNHI} from 'nhi-validator'

let value = 'zvb97xq'

validateNHI(value) // => true
!value.toUpperCase().startsWith('Z') && validateNHI(value) // => false
