About Us

Our home is Tauranga.

Why us?

The team at Generator’s aim is to provide business owners with a boutique service based on three fundamentals:

  • Personal service – you know the team and we know you 
  • No Surprises – you know your tax liabilities and when to pay them (and we remind you to do so)
  • Agreed fees – we agree fees and payment terms with you before we start (no surprises there either)

Whether you are new to business or have been at it forever, it is always good to have a team at the end of the phone or email who can promptly answer your questions. If we can’t help, we know someone who can, including a lawyer or three, a plumber, electrician, painter, earthmover…. Just ask!

We are Chartered Accountants, members of the Chartered Accountants of Australia and New Zealand (CAANZ) – this means we are held to a higher ethical standard. We undertake at least 40 hours of professional development every year and are subject to regular peer reviews.

We are Xero Accountants, through and through. The whole team is Xero Advisor Certified.  We are also experienced with a range of Xero add-ons that make life easier for business owners.

If you think we are a good fit for your business – we’d love you to join us!

Margaret has been accountant for more years than she is prepared to admit, her passion is to see local businesses succeed.

The accountant in her means she get immense satisfaction from seeing things balance, more importantly she likes to see business owners achieve what they planned when they went in to business.

Often seen out on her Spyder, she loves travelling around NZ and the world, catching up with family and friends.

Jo works with our customers on a daily basis making sure their Xero data looks good and they are getting regular reports. She can help with Xero training, payroll and getting your tax sorted.

Out of the office, Jo likes to spend time out on the coastal tracks close to home followed by long leisurely aperitifs on the deck with family.

Sonia Diacono

Office Manager

Sonia is the go to person for everything the accountants don’t do in our office (and some of those they do). She makes great coffee, keeps everyone organised and generally runs the show.

When not in the office, Sonia can be found enjoying the outdoors with her family, sampling the occasional vino, and travelling (when we can).
