Free for farmers to register and use, always
The verified record for pastoral beef.
KaiProva keeps each animal’s tag, weights and history in one private record, so the work you put in stays visible after the animal leaves your farm.
No new tag. No new weighing system. No requirement to sell.
Example animal record
Why it matters
The animal moves. Its history often doesn’t.
KaiProva keeps one private record through every farm, showing where the animal has been and how it has grown. You choose when to share it.
How it works
Start with your current animals, tags and weighing equipment.
Upload a reader file using the official tags on your animals.
Add each new weigh session. The picture gets clearer as the animal grows.
Keep it private, or share it with a chosen processor or programme when an opportunity fits.
What it opens up
Start with a private view on farm. Use the same history when an opportunity or result comes back.
Each farmer adds to the same history, showing where the animal has been and how it has grown. If part of the history is missing, the gap stays visible.
Building
With your permission, a processor looking for animals like yours will be able to find you. We’d rather label this than demo it.
The evidence goes forward to processors and buyers. The result comes back to the farmers who raised the animal, so they can see what worked.
A buyer asked a simple question: where will the beef come from, and what can we say about it?
Answering it meant piecing together farms, spreadsheets and separate systems — and even then, nobody could point at an animal and say where it had been or how it had grown. The animals were there. The record wasn’t.
That gap became KaiProva.
Carbon calculation
You may already be collecting the evidence.
How efficiently an animal grows is a major driver of its carbon footprint. KaiProva connects the weights you already record to each animal and keeps that growth history together.
AgResearch modelled the carbon footprint of New Zealand pastoral young dairy beef finished at 10–18 months, across 54 production scenarios.
At processing the record closes, and each individual animal gets an indicative carbon estimate calculated from LCA modelling, with accuracy improving as the science grows.
New Zealand young dairy beef
32–48%
lower carbon footprint than the Beef + Lamb New Zealand Class 9 baseline
New Zealand pastoral young dairy beef, finished at 10–18 months. The result does not extend to other countries, stock classes or production systems.

What’s next
Three clear stages, so you can see what works today and where KaiProva is heading.
Now
Register official tags, add weights and keep a clear view of what is growing on your farm.
Building
Each farmer continues the same animal history instead of starting again.
Later
Bring producers together, agree supply earlier and keep the animal connected through to payment.
Common questions
The basic record is free for farmers. Register animals, add weights and keep your private record at no cost. Registering does not guarantee a buyer or a premium.
No. KaiProva uses official tags and compatible reader files from your current equipment.
Your record starts private. You choose what to share and with whom. KaiProva does not sell farm data.
No. Registering an animal never lists it for sale and does not commit you to a buyer, price or delivery date.
KaiProva connects the official identity, dated weights and farm history, and verifies that the record is complete and follows the Protocol. A claim is only made when the record, and the science behind it, support it.
Farmers, growers and finishers keep the record. Processors and buyers use the evidence at the other end. Programmes and research groups will be able to run their own cohorts on the same record — that part is still being built. KaiProva is open to all of them; it isn’t owned by any one buyer.
