Selling a property with ETS-registered forest? Here's what has to happen

If your property includes forest land registered in the Emissions Trading Scheme, that registration doesn't just sit quietly in the background of your sale. It has to transfer to the new owner. MPI treats this as a mandatory transfer of participation, not something either party can opt out of or let lapse, and getting it wrong can leave you personally liable even after you've moved on.
This guide covers what actually has to happen when ETS-registered forest land changes hands, regardless of who manages your registration. Then, because a lot of the practical steps depend on that, we've covered what it looks like specifically if CarbonCrop is your registration manager.
In this guide we'll cover:
What has to happen, regardless of provider
Post-1989 registered forest land carries ETS obligations that attach to the land itself, not to whoever happens to own it at the time. When you sell, those obligations, and the right to keep earning credits, transfer with the title. There's no version of selling ETS-registered land where the registration just stays with you, or just disappears.
MPI needs to be told about the change of ownership, within 20 working days of the settlement date. That's the deadline we work to for our own customers, and it's an MPI requirement rather than a CarbonCrop one, though if you're managing your registration another way it's worth confirming the specifics directly with MPI.
Whoever manages the registration, whether that's you directly, another consultant, or CarbonCrop, will also need to deal with the final emissions return.
This covers any change in carbon stock on the land up to the point of transfer, closing out the seller's side of the ledger before the buyer's obligations begin.
Tip: start the conversation with whoever manages your registration as soon as you have a signed Sale and Purchase Agreement, not just before settlement. The paperwork is straightforward if there's time to do it properly, and much less so if it's rushed in the final week.
What happens to your carbon credits
This is the part that catches people out, because "carbon credits" actually covers two different things that behave in completely different ways.
The ETS tracks a running unit balance for the land itself, the net total of units earned since registration. That balance stays with the land and transfers automatically to the new owner. There's nothing to action, and it's not something a seller can choose to keep.
Your actual NZUs, the ones already issued into your own holding account, are different. Those belong to you personally, and they don't automatically transfer to the buyer just because the land does. Whether any change hands is a private commercial matter between you and the buyer, to be negotiated and documented in the Sale and Purchase Agreement itself, not in whatever novation or transfer paperwork your registration manager prepares.
Talk to your solicitor about how, or whether, you want to treat your NZU balance in the sale contract, before you sign the Sale and Purchase Agreement.
If CarbonCrop manages your registration
If CarbonCrop already manages your ETS registration, most of the process above is handled for you. Here's specifically what that looks like.
As soon as you have a signed Sale and Purchase Agreement, let your account manager know. We prepare a Deed of Novation, the legal document transferring your rights and obligations under your CarbonCrop management agreement to the new owner, using details you and the purchaser provide. You, as the retiring party, and the new owner, as the substitute party, each sign it. From the effective date, the new owner steps into your position under the agreement.
From there, we lodge the "Tell us about a transfer of ETS responsibilities" form with MPI on your behalf, and submit your final emissions return. The new owner's holding account also gets set up as part of the deed, with them consenting to CarbonCrop acting as their agent so returns and transactions keep running without a gap.
You have three options for how to handle your CarbonCrop agreement when you sell.
Novate the agreement. The new owner takes over your existing agreement through the Deed of Novation. No break fees apply, and it's the simplest option if they're happy to continue with CarbonCrop.
New agreement. The new owner signs their own agreement with CarbonCrop on our then-current terms.
Terminate. If the new owner doesn't want CarbonCrop involved at all, you can terminate the relevant Schedules or the whole Agreement on written notice. Break Fees apply, as set out in your contract.
As the vendor, you're generally responsible for the costs of exiting cleanly: notifying MPI, preparing and submitting your final emissions return, and any outstanding balance on your existing CarbonCrop service fee invoice. We'll invoice these, and your solicitor may arrange payment as part of settlement. Costs vary, so it's worth asking your account manager for a current estimate rather than guessing.
Not sure which of the three options fits your sale? Talk to your account manager early, before you're locked into settlement terms.
If someone else manages it, or you manage it yourself
If your registration is managed by a different consultant, or you handle it yourself directly with MPI, the mechanics will look different. There's no Deed of Novation in the CarbonCrop sense, and the specific forms and process will depend on how your registration is currently structured. The obligation to notify MPI of the transfer still applies, that part doesn't change based on who's managing it, but the exact steps to get there are ones we're not in a position to walk you through in detail. Whoever currently manages your registration, or MPI directly, is the right place to start.
Common questions
Do I actually have to transfer the registration? Can't I just let it lapse?
No. Transferring participation is a legal requirement under the ETS when post-1989 registered forest land is sold, it isn't optional. MPI can hold you liable if a transfer isn't notified correctly, so it's worth getting right rather than leaving to chance.
What if the buyer doesn't want to continue with CarbonCrop?
That's fine, and it's specific to CarbonCrop customers rather than a general ETS rule. A new agreement direct with CarbonCrop, or you terminating your management agreement and paying Break Fees, are both available. Talk to us early so we can plan around the buyer's preference.
How long does the whole process take?
If CarbonCrop manages your registration, the Deed of Novation can usually be prepared and signed around the time of settlement. The regulatory side has a firmer deadline: our understanding is that MPI needs to be notified within 20 working days of the settlement date, and we manage that on your behalf once you've told us the sale is happening.
I'm only selling part of my property. Does this still apply?
Partial sales, and other special situations like recently harvested but unstocked land, trusts, or inherited land, involve extra considerations outside this general guide. If CarbonCrop manages your registration, talk to your account manager and we'll walk through what applies to your specific situation.
This guide is general information to help you understand the process. It isn't legal, tax, or financial advice for your specific circumstances. Please talk to your own solicitor and accountant, and to whoever manages your ETS registration, before making decisions about your sale.
If CarbonCrop manages your registration, talk to your account manager about your sale. If you're not yet a CarbonCrop customer and want to understand your options, email us at hello@carboncrop.com.
