Further details are available where client permissions allow.
What the work involved: Over more than 18 months, Nigel built the data-extraction pipeline, developed verification checks, contributed economic modelling and calculation work, and helped write the report.
Why it mattered: Inland Revenue used tax administration data, public data and information collected from participants to analyse the effective tax rates of 311 high-wealth families.
What the work involved: At Infometrics, Nigel developed council economic monitoring systems in New Zealand.
Why it mattered: The systems helped councils track local economies, compare places, brief elected members and explain change over time.
What the work involved: Economic state-of-play reporting and economic and demographic growth assumptions for council planning.
Why it mattered: Long-term planning needs a clear view of population, migration, labour-market, business and sector trends under uncertainty.
What the work involved: Data science and economic assessment work to support a local growth and planning context.
Why it mattered: Growth decisions need clear evidence about local activity, jobs, business structure, population and the assumptions behind the numbers.
What the work involved: Finding official data, checking source quality, recording caveats, and turning source material into report-ready tables and figures.
Why it mattered: Public-sector decisions often need a clear line between official baseline data, client assumptions, modelling judgement and conclusions.
What the work involved: Framework work for economic impact assessment, including clear treatment of assumptions, local effects and evidence limits.
Why it mattered: Public-sector clients often need to separate total activity from activity that is likely to be new to the local area or New Zealand.
What the work involved: Growth assumptions, forecasting and scenario testing for council decision-making.
Why it mattered: Forecasts influence infrastructure, housing, service planning and policy choices. The key assumptions need to be clear.
What the work involved: Economic context and evidence to support regional screen-sector strategy work.
Why it mattered: Sector strategies need a realistic view of local strengths, constraints and economic contribution.
What the work involved: Helping turn monitoring and policy questions into practical data needs.
Why it mattered: Good monitoring starts with clear questions. The work needs to show what can be answered now, what needs better data, and what judgement is needed.
What the work involved: Analysis of business births and deaths in regions following Covid-19 for several clients.
Why it mattered: Business-demography evidence helps explain local resilience, disruption and recovery after a major economic shock.
What the work involved: Development of data tools and profiles that brought together official statistics, administrative data, modelling outputs, tables, charts and downloadable reports.
Why it mattered: Profiles and dashboards make complex regional and industry data easier for councils and organisations to use repeatedly.
What the work involved: Nigel is a co-founder, CTO and founding director of Hello Cashflow, and provides technical, modelling and advisory services to the company. The product connects to accounting software and turns financial data into clearer cashflow insight for business owners.
Why it mattered: Hello Cashflow shows how modelling, data tools and plain-English reporting can help small businesses make better decisions from information they already hold. In 2026, Hello Cashflow was part of Creative HQ's Fintech Lab 2026 cohort and was recognised as Judges Choice at the Kiwibank Start Up Pitch Breakfast during FinTechNZ Hui Taumata.
