Payroll giving is available in New Zealand. Talk to your HR or payroll administrator about signing up to make regular donations via your payroll. Parkinson's New Zealand has already been added to the approved donee lists of a number of organisations including Telecom and the Ministry of Social Development, as well as payroll provider iPayroll.
Your donation will be made directly from your payroll pre-tax, meaning that you would receive an immediate 33.33% tax credit. You can chose how much you would like to give and how frequently and you can change this at any time.
