Nicola has a background steeped in finance, having spent many years in domestic banking both here and in the UK. Two years in merchant banking in London followed by five years as a corporate foreign exchange dealer, her last role being in ANZ Auckland treasury.

Raising a family of four sons and growing a business dictated her and her marketer husband Andrews next phase of life. The purchase of a business and relocation to Warkworth in 2000 began a time of much personal growth and many challenges, industry changes, expansion, diversification, and recession. As the GFC hit home Nicola took the helm of the business while Andrew returned to a corporate role. Successfully preparing the business for sale and a seemly industry exit post GFC was one of the hardest times but in hindsight a highlight.

Nicola had just launched a start-up – seeing a niche in what is now termed the virtual assistant market however finances dictated she return to banking and finance.
