About us

“It’s refreshing to have Chartered Accountants who see more than compliance. Since working with iif we’ve been able to make better business decisions, knowing we’re on the right path.” - John Roche, AlphaNZ Technology

In our experience, business owners get the most from their Chartered Accountant when they’re talking about more than accounting and tax. The value from accountants from conversations about cashflow, profitability, and working capital. Conversations about structuring, risk, investments, property, and wealth creation. Then through conversations tax – this is the end, not the beginning. We’re focused on these conversations, and involving your other professionals (like your lawyer, and broker) to make sure nothing falls through the gaps, and that your Financial Blueprint is in good shape.
