What is the dividend withholding rate between Australia and New Zealand?

Under the Australia-New Zealand tax treaty, the withholding rate on dividends is 15% for portfolio investors (general rate). A reduced rate of 5% applies when the beneficial owner is a company holding a qualifying ownership stake (typically 10% or more of voting stock). Note that the reduced rate requires the recipient to file the appropriate treaty benefit claim form before payment. This 15% rate compares to a median of 15% across Australia's 48 active treaty partners, and 15% across New Zealand's 32 active partners.
