Trading NZUs: How the Market Works
Once you’ve earned NZUs, you have options. Hold them, sell them, or use them for offsetting. Understanding the market helps you make informed decisions.
Market Structure
Primary Market (Auctions)
The government sells NZUs through quarterly auctions. Key features:
- Frequency: Four auctions per year (March, June, September, December)
- Reserve price: Minimum price at which units sell (currently $68)
- Volume: Pre-set quantity offered each auction
- Participants: Must be registered in NZETR
If market prices are below the reserve price, auctions may not clear (no units sold). This has happened repeatedly in recent years.
Secondary Market
Most trading happens on the secondary market — direct transactions between buyers and sellers:
- Spot transactions: Immediate delivery and payment
- Forward contracts: Agreement to trade at a future date
- Over-the-counter (OTC): Bilateral deals, often through brokers
There’s no formal exchange. Prices are discovered through negotiation and reported by price-reporting agencies.
Price Discovery
NZU prices are set by supply and demand. Key reference prices:
- Spot price: Current market price for immediate delivery
- Forward price: Agreed price for future delivery
- Auction clearing price: Price at which government auctions clear
Price reporting services (like CommTrade, Jarden) publish daily or weekly price assessments.
Selling Your NZUs
Selling Through Brokers
Most forest owners sell through carbon brokers who:
- Find buyers for your units
- Handle transaction mechanics
- Provide market intelligence
- Charge a commission or margin
Typical broker arrangements:
- Commission-based: 2-5% of transaction value
- Fixed margin: Broker buys at X, sells at X+margin
- Aggregation: Pool your units with others
Direct Sales
You can sell directly to:
- Other NZETR participants
- Compliance buyers (emitters)
- Corporate offset buyers
- Other forest owners
This avoids broker costs but requires:
- Finding your own buyers
- Negotiating terms
- Managing settlement
- Understanding market value
Transaction Process
- Agree terms with buyer (price, quantity, settlement)
- Initiate transfer through NZETR
- Buyer confirms the transfer
- Units move to buyer’s account
- Payment settled separately (bank transfer, etc.)
The NZETR handles unit transfer but not payment — that’s between buyer and seller.
Buying NZUs
Why Buy?
You might buy NZUs to:
- Cover surrender liabilities
- Offset emissions elsewhere
- Speculate on price increases
- Meet contractual obligations
Buying Options
Government auctions:
- Quarterly opportunities
- Must bid above reserve price
- Competitive bidding process
- Minimum quantities may apply
Secondary market:
- Available anytime
- Prices vary with market
- Through brokers or direct
- More flexible on quantities
Contracted purchases:
- Forward agreements with sellers
- Lock in future supply
- Price certainty
- Counterparty risk
Market Dynamics
Supply Factors
What increases supply:
- Forestry allocations (more forests, more units)
- Holders selling stockpiles
- Government auction sales
- Voluntary participation increasing
What decreases supply:
- Reduced forestry allocations
- Holders banking units
- Government reducing auction volumes
- Forests exiting the scheme
Demand Factors
What increases demand:
- Higher emissions from covered sectors
- Approaching compliance deadlines
- Anticipation of price increases
- Corporate voluntary offsetting
- Reduced free allocation to industry
What decreases demand:
- Economic downturn (lower emissions)
- Increased free allocation
- Policy uncertainty (wait-and-see)
- Holders drawing on stockpiles
Price Signals
Key things that move prices:
- Government policy announcements
- Auction results
- Economic data (activity = emissions)
- Climate policy developments
- International carbon market movements
Market Participants
Compliance Buyers
Large emitters who must surrender units:
- Fuel importers
- Industrial manufacturers
- Electricity generators (indirectly)
They’re the ultimate demand source.
Forestry Sellers
Forest owners like you who earn units through sequestration.
Aggregators
Consolidate units from many small forests, sell in bulk to compliance buyers.
Traders and Speculators
Buy and sell to profit from price movements. Provide liquidity.
Brokers
Facilitate transactions between buyers and sellers. Earn commissions.
Timing Your Sales
Arguments for Selling Early
- Lock in known value
- Fund establishment or maintenance costs
- Reduce exposure to price drops
- Simplify tax planning
Arguments for Holding
- Prices may rise over time
- Defer tax liability
- Maintain buffer for contingencies
- Policy direction favours higher prices
Hybrid Approaches
Many owners:
- Sell some regularly (cash flow)
- Hold some as reserve (buffer)
- Sell opportunistically (price spikes)
There’s no perfect strategy — it depends on your circumstances and risk tolerance.
Market Risks
Price Volatility
NZU prices have ranged from under $2 to over $80 in the scheme’s history. Factors beyond your control can move prices significantly.
Liquidity Risk
In a small market, you may not always find buyers at your desired price. Large sales can move the market.
Policy Risk
Government decisions affect the market:
- Cap settings
- Auction volumes
- Reserve prices
- Eligibility rules
Policy changes can rapidly affect prices.
Counterparty Risk
In direct transactions, there’s risk the other party doesn’t perform. Use established brokers or escrow arrangements for large transactions.
