Our Team


Garth Parkinson

North Island Sales Manager

Garth grew up on the Hibiscus Coast, before moving into Auckland city to study.  Garth holds a Hospitality Management Diploma from AUT (he graduated top of his class) and he has held various hospitality roles internationally over the years, including extensive work in Europe, the USA, Canada and England.

He co-founded Barluga, a luxury wine and cocktail bar in the beautiful Wanaka in New Zealand’s South Island, during one long stint in the area.  In May 2005 he met Chris Smith who installed WizBang onetap POS system in his bar.
In 2014 Garth was head hunted and became a valued member of our sales team.  Garth has worked in many different roles and styles of business in the hospitality industry.  Because of his extensive experience, and ownership of a successful bar, he instinctively understands what each unique business needs from our onetap system.

Chris Smith

National Sales & Distribution Manager

Chris is one of the longest serving members of the WizBang family, and in July 2015 celebrated being with the company for 10 years.

He is a born and bred Cantabrian, having lived in Christchurch for over 30 years.  He spent many of his younger years working in the hospitality industry where he was a trusted team player.  One of his highlights from this time was assisting the owner of a well known pizza restaurant in Christchurch open four more restaurants and then franchising of these new stores.
Chris Smith-321
Chris holds an Advanced Certificate in Computer programming and is passionate about new technologies.  His more recent background prior to his current role includes both sales and management roles within the computer retail industry.  Before working for WizBang he was successful in both sales and installation of onetap software, working for EFTCO, a reseller for onetap software.  In 2005 WizBang approached him to work directly for them to help establish a second office in Christchurch.  He jumped at this opportunity as he was passionate about both the onetap software and the hospitality industry, and it appealed to his pioneering nature.

Chris owes much of his success to a strong focus on building and retaining relationships with our clients. He loves seeing businesses within the hospitality industry succeed and is always willing to go the extra mile to ensure our clients thrive.

The hospitality industry was hit hard after the Christchurch earthquakes. Fifty two percent of our clients in Christchurch were initially unable to trade.  All of those who have reopened have returned to the onetap system. This is a reflection not only of a great product but of the integrity of a sales manager committed to both company and customers.

Chris lives in Christchurch with his wife, three kids and the family border collie. Over the years Chris has been heavily involved in the local Surf Life Saving Club. He raced inflatable rescue boats and won numerous national titles.  His present day interests include new technologies and spending time with good friends.

John Hansen

CEO & Founder 

John is a visionary thinker and irrepressible optimist with innovation in his DNA. His innate curiosity and enthusiasm for a future shaped by possibilities is the driving force behind his quest to go beyond the limits of current technology and capability.
He is a science graduate with extensive experience in digital electronics, design of microprocessor based telemetry systems, production control systems, and commercial software development, primarily in the field of retail POS systems. He also brings years of commercial experience into the company having been involved in other enterprises prior to WizBang Technologies.
Soon after graduating in physics in 1972, John found himself working for Cutler-Hammer NZ designing microprocessor supervisory, control and data acquisition (SCADA) systems for South Australian Railways and Sydney County Council. 
This experience in the early adoption of a new disruptive digital technology inspired John’s “possibility” mind-set and set him on a trajectory of innovation.
He started his own electronics and software design consultancy and was commissioned to design many industrial and commercial systems. Among these was a microprocessor weighing and production control system for wire manufacturing, a spot welding machine digital controller, a messaging system for large electromagnetic and LED outdoor advertising displays, a numerical machine controller for the manufacture of printed circuit boards, a digital codec for wireless data transmission and radio paging and a vehicle speed detection system.
With this experience behind him, John saw the possibility of developing commercial software with scalable global potential and took the opportunity to work for an enterprising South African company to develop a complete financial and point of sale system for furniture and clothing retailers, known as Furnpac and Ragpac.
Returning to New Zealand in 1987, John co-founded Pacific Business Systems (now Excellent Software and Services) and developed a successful big ticket retail point of sale system known as Retail-Plus and a hire purchase ledger financial control system.
In 1997, John and his family who had all become confirmed café junkies were inspired to find a way to make life easier for waiters. The dream was to create a ground-breaking and innovative new hospitality point of sale system, encompassing wireless hand held technology for taking orders from tables. Wi-Fi was not available for portable devices at the time, so the solution required the design of a plug-in digital wireless transceiver circuit board for the Palm Pilot PDA and a corresponding wireless base station transceiver.
The solution John designed utilised a UHF FM narrow frequency band, with a range of 300 metres. Extremely low power consumption was a design objective with four days battery life being achieved through the use of CMOS technology.  In order to keep hardware production costs down, collision avoidance, radio noise filtering, and error checking and correction were designed into the transceiver software drivers rather than the hardware.
The success and reliability of this mobile solution, known as WizBang Waiter at the time, was the genesis of WizBang Technologies.
Today, John leads WizBang Technologies, with the single-minded purpose of driving innovation and growing global distribution channels.
In his time off, you’ll find John sampling local hospitality with family and friends, keeping fit pounding the streets or swimming at the local beach where he currently lives in Millwater, Auckland. He also somehow finds time to fuel his fascination for science and technology, especially cosmology which seems to resonate with his curiosity about the nature of things. John is also passionate and concerned about environmental issues, food quality, food supply and organics, and thinks the extraordinary movie “Food, Inc” should be mandatory viewing for all!
