What Tregaskis Brown does

Tregaskis Brown, operating under the trade name TBL Consulting, is a Wellington-based professional services consultancy founded in 2002 and led by founder and partner Karen Tregaskis. The firm employs between 11 and 50 people and delivers advisory services to New Zealand public sector organisations, private sector firms, and not-for-profit entities, with a clearly primary focus on government clients accessed through its Tier-1 status on the New Zealand Government Procurement's All-of-Government panel.

The firm delivers eight discrete consulting service lines: Sound Governance, Robust Investment and Asset Management, Compelling Business Cases, Operational and Strategic Reviews, Executive Facilitation and Business Planning, Fractional Executive Support, Delivering Enduring Change, and Capability Uplift and Training. Engagements are scoped around complex or contested organisational problems, alignment of systems and people to deliver public value, and building decision-making capability. Reference clients include the Department of Internal Affairs (Te Tari Taiwhenua), the APEC 2021 New Zealand host year, and Victim Support.

Commercially, TBL operates a project-based professional services model with revenue generated through fixed-fee project engagements, time-and-materials advisory work, and consulting retainers, including fractional executive placements that create a recurring element. Go-to-market is sales-led, consultative, and relationship-driven, anchored on panel access, direct business development, and a published case-study portfolio on its website (tblconsulting.co.nz). Pricing is negotiated per engagement and not publicly disclosed. There is no disclosed product, software platform, or proprietary technology; the firm's value proposition rests entirely on senior advisory expertise and public sector delivery credibility.
