Beyond the first draft
The Bid Lab is coming

Your next tender deserves more than generic templates and copy paste content

You're competing for contracts against companies with dedicated bid teams, professional designers, and unlimited resources. Your expertise deserves tender responses that match your ambition.

HelloYellow Bids levels the playing field by bringing corporate-quality tender development to NZ construction and infrastructure businesses, without the corporate overhead or inflated fees.

Based in Wellington, I work with contractors and consultancies across New Zealand who are tendering regularly and want their submissions to actually reflect the quality of their work.

Strategic Differentiation

I don't just respond to RFTs. I develop competitive tender strategies that give evaluators a reason to choose you over everyone else.

Premium Design

Using professional InDesign expertise to transform technical tender responses into sharp, visually compelling submissions that stand out.

Personal Partnership

Every tender receives my personal attention and expertise. No junior staff, no outsourced work, no surprises.

Your Strategic Proposal Partner

I'm a Wellington-based bid writer and tender strategist specialising in NZ construction, engineering, and infrastructure.

After helping businesses secure millions in contract wins, I now focus exclusively on NZ SMEs in the built environment (the companies doing genuinely great work who just need someone to help them communicate it properly in tenders).

My approach combines tender strategy, compelling writing, and premium InDesign design. I work across the full bid lifecycle, from initial RFT analysis and win theme development through to final submission and debrief analysis.

I work with companies across Wellington and throughout New Zealand, on everything from one-off strategic tenders to ongoing monthly retainer support.

A few things worth knowing:

100% on-time delivery record across all projects
