01 What we do
Four practices, one firm
Northstar Advisory works with mid-market New Zealand companies — typically $20M–$500M revenue, 50–800 staff — on the strategic questions that are too important to answer in a Monday morning meeting.
Growth strategy
Market entry, adjacency analysis, acquisition due diligence and three-year plans with quarterly milestones. We build the model, stress-test the assumptions and stay engaged through execution.
Board governance
Board effectiveness reviews, skills-matrix assessments, chair coaching and succession planning. We work with NZX-listed and large private boards.
Operational efficiency
Process mapping, cost-structure analysis, lean implementation and KPI frameworks. We identify the 20% of changes that drive 80% of the gain.
M&A advisory
Buy-side and sell-side strategic advice — target identification, commercial due diligence, integration planning and Day 1 readiness.
02 Our approach
How an engagement works
Discovery (2 weeks)
We interview your leadership team, review financials and visit operations. The output is a scoping document with a confirmed question, timeline and fixed fee. If you decide not to proceed, the discovery is free.
Analysis (4–8 weeks)
Deep work: market sizing, benchmarking, financial modelling, stakeholder workshops. We present interim findings at the midpoint so we can correct course before the final report.
Recommendation (1 week)
A written report with three to five prioritised recommendations, each with an investment case, risk assessment and implementation steps. We present to the board if requested.
Execution support (optional)
Monthly check-ins, quarterly progress reviews, and ad-hoc advisory on a retained basis. Most clients retain us for the first twelve months of implementation.
Fee transparency
Every engagement is fixed-fee, agreed before we start. Our typical range:
- Board governance review: $18,000–$35,000
- Growth strategy: $40,000–$90,000
- Operational efficiency: $30,000–$65,000
- M&A advisory: $50,000–$120,000
All fees are plus GST. Travel outside Wellington is at cost.

Growth strategy
National logistics company — Australian market entry
Assessed three entry modes (greenfield, JV, acquisition) and recommended a bolt-on acquisition in Melbourne. Supported due diligence and Day 1 integration. The Australian operation broke even in month fourteen.
Break-even in 14 months · $38M acquisition
Board governance
Agricultural co-operative — board effectiveness review
Skills-matrix assessment revealed a gap in digital and export experience. Recruited two independent directors, restructured committee charters and coached the chair through a contested AGM. Board satisfaction scores rose from 3.1 to 4.4 out of 5.
Board satisfaction: 3.1 → 4.4
Operational efficiency
Regional construction firm — cost-structure review
Mapped 14 end-to-end processes and identified $2.1M in annual savings through procurement consolidation, scheduling software and a revised subcontractor framework. Implementation cost: $380K. Payback in under eight months.
$2.1M annual savings · 8-month payback

05 What we believe
Five principles
Strategy is a decision about what not to do. If the plan does not require saying no to something, it is not a strategy.
Boards should govern, not manage. The best board we ever worked with asked three questions per meeting and made one decision.
Efficiency without purpose is cost-cutting. We only pursue operational gains that fund a strategic priority the company has already chosen.
Fixed fees eliminate the incentive to over-scope. We quote before we start and absorb overruns ourselves.
Mid-market companies deserve the same quality of advice as large corporates, without the overhead of a global firm.
