I engaged with IBAS to advise one of my clients. But ended up also using their Tax Services. Chantel and the team’s work had been done thoroughly and the outcome was extremely reassuring. I would be very happy to recommend your services to anyone seeking specialist tax advice.
Mark Auckland
Chantel is a pleasure to deal with and has always been flexible and reliable. I wish her well and highly recommend her personally and professionally.
FionaAuckland
As a self-employed insurance broker, I find it difficult fitting in time to keep my accounts up to date - but with the team from IBAS supporting me I can now concentrate on my clients

We have been working with Marian for years. She proves exceptional service, being both professional and highly personable.
Andrea Wellington
“We have worked with Chantel & Marian for a while now, and we are very happy with their service, professionalism, and expertise. They have helped us organize and streamline our finances and they have given us great advice and guidance on eliminating unknown, and unwanted, fees and costs. We will continue to employ their services and highly recommend them to others who are looking to organize and consolidate their bills, expenses, assets, and income under easy-to-understand reports and spreadsheets.”
LauraTauranga
“Chantel is a gem, very smart and very willing to do things I can’t! I’ve had quite a few laughs with her, and that’s something that is sorely needed for all of us at this time. Every year was daunting realising my tax affairs needs to be finalised, but Chantel has completely transformed this anxiety and she takes away the stress on a yearly basis, always with a smile. I’m so grateful for finding her, and I will spread the word wherever I go”.
JoannaAuckland
“For the first time in a long time I have peace of mind that someone is staying on top of my day-to-day financial affairs, thanks to my financial advisor who referred me to IBAS. They have gone beyond my expectations and handles not only my “books” but my Yearly Financials and Taxes for both my company and personally. They have also clarified and helped me understand issues that previously seemed overwhelming. Overall, a huge burden has been removed.”

Frequently Asked Questions

Still have a few questions on your mind? We’re happy to answer them for you.

A professional tax agent reduces your risk of errors, ensures full IRD compliance, and typically finds deductions you’d miss on your own. We give you peace of mind and maximise your return.

Usually your income statements, IRD number, and details of any overseas income or rental properties. Requirements vary by situation — we’ll walk you through exactly what’s needed once we know your circumstances.

We follow strict data security practices, and access to your personal and financial information is restricted to authorised IBAS staff only.

Of course! Our bookkeeping services include the historical clean-up of your documents. We’re here to help you get back on track, whatever it takes.

Just get in touch by email or through our contact form. We’ll guide you through the documents needed, then file your return and manage your refund — or set you up with ongoing bookkeeping if that’s what you need.
