RANZ Hub

RANZ Hub is the New Zealand roofing industry's home for learning, the Code of Practice, and on-site compliance. Built by the Roofing Association of New Zealand for installers, apprentices, fabricators, designers, and certified roofing companies.
Whether you're sitting your apprenticeship, sharpening your knowledge between jobs, or settling a question on the roof, RANZ Hub gives you the right answer from sources you can trust — the MRM Code of Practice, NZBC E2/AS1, and material-specific manufacturer guidance.
WHAT'S INSIDE

Daily Quiz — three quick questions, every day. Builds streaks, XP, and league standing without eating your smoko break.
Learn — chapter-by-chapter Code of Practice content broken into modules you can knock off one at a time. Bookmark, revisit, track progress.
Ask — type a roofing question, get a sourced answer drawn from the Code of Practice and approved technical material. Photos optional.
Flashing Builder — sketch a flashing's cross-section, set the legs, bends, hems and slope, see a real 3D mitred run. Get a labelled PDF spec ready to email straight to your merchant or fabricator. Works offline — emails queue and send when reception comes back.
How To — step-by-step photo guides for tricky details: penetrations, ridges, valleys, roof-to-wall flashings, and material compatibility.
Compliance Wizard — Building Act 2004 decision tree. Quickly tell whether work needs a building consent, where E2 applies, and what the Determinations say.
Toolbox Talks — short, plain-English safety briefings ready for site.
Practice — drill specific topics until you've got them locked in.
Weekly Challenge — go up against the rest of the industry on a themed quiz. Real-time leaderboard, tier badges.
Knowledge Map — see where you're strong and where to focus next.
Forum — ask the rest of the industry. Threaded discussion by trade area, moderated by RANZ.

OFFLINE-FIRST
The Hub is built as a progressive web app. Once you've loaded it on a good connection, learning content, the daily quiz, the Flashing Builder and the Code of Practice are available offline. Things you do offline — emails, answers — sync automatically when you're back in reception.
