(m: 027 503 0487, e: [email protected])

Alistair and Joanne Stapp are both Chartered Accountants who’s experience range from large multi-national corporates to small owner managed businesses. One common factor they have found among all these companies is that managing cash flow is crucial. Even the best managed business, with supportive lenders and clients, are still likely to require additional support at times. Therefore, they believe that the solution Interface offers is important, especially in New Zealand where smaller businesses are the backbone of the economy.

Outside of work most of their spare time is taken up by their 3 kids and yellow Labrador. Any time left over after that they both try to stay active and fit. Having lived in both South Africa and London, they are now proud kiwis and call New Zealand home.
