Selling Your Home Privately vs Using an Agent in New Zealand: The Real Calculation

The arithmetic looks obvious. A real estate agent charges roughly NZ$27,000 to NZ$37,000 in commission and marketing on a NZ$900,000 home. Sell it privately, spend NZ$689 on a Trade Me Property listing and NZ$500 on professional photos, and pocket the difference. NZ$26,000 saved. Easy.

Then you speak to someone who tried selling privately and the story changes. They spent eighty days fielding lowball calls. They priced wrong—too high and nobody came, too low and they left NZ$40,000 on the table. The eventual sale price was less than what an agent would have achieved. The ‘saving’ was a loss.

The truth is more nuanced. Here is how to decide which camp you belong to, with verified numbers from New Zealand’s major providers.

The Case for Private Sale

On a NZ$900,000 home, the potential saving is NZ$27,000 to NZ$35,000 after marketing costs. That is real money. You avoid signing a sole agency agreement that locks you in for 90 to 120 days. You control open homes, marketing spend, and which offers to accept or reject.

The practical steps are straightforward. Hire a property lawyer—this is non-negotiable in New Zealand. List on Trade Me Property (NZ$599 + GST for a 3-week standard listing) and on realestate.co.nz via a third-party platform such as PrivateSales.co.nz (around NZ$299 + GST for a 4-week listing). Professional photography costs NZ$400–NZ$700 from a real estate specialist. Arrange open homes, negotiate directly, and complete the transaction through your lawyer.

Private sales work best when you already have a buyer lined up—a family member, a neighbour who expressed interest, or someone who approached you directly. They also work when you have recent comparable sales data from Homes.co.nz or OneRoof to price accurately. The online portals have narrowed the information asymmetry that once justified the agent’s role.

The Case for Using an Agent

An agent does not just list a property and wait. They build competitive tension. They contact every buyer who has registered interest in similar properties over the past six months. They call agents who sold comparable homes to find buyers who missed out. They manage the price conversation—saying “the vendor is not accepting less than that” is harder for a private seller to say convincingly, because the buyer knows the seller is also the negotiator.

The buyer psychology problem is real. When a buyer sees a private sale, they know roughly what the agent commission would have been. They mentally discount their offer by a portion of that saving. On a NZ$900,000 property, buyers typically deduct 2% to 3% of the sale price—NZ$18,000 to NZ$27,000—because they assume the seller is pocketing the commission. The saving disappears into the buyer’s pocket.

An agent also brings professional pricing that matters in a market without perfect information. Online estimates from Homes.co.nz and OneRoof are directional at best. An agent who has sold ten homes on your street in the past year knows what each one actually sold for, how the property differed from the online profile, and what buyer reactions were at each price point. That knowledge directly affects the final sale price.

Agents also use auction and deadline sale processes to create urgency. At auction, buyers compete in real time, often pushing the price above reserve. In a multi-offer deadline situation, agents orchestrate a tight timeframe that prevents buyers from waiting for a lower price. Private sellers rarely replicate this effectively.

The Hybrid Options

Several New Zealand providers offer middle paths that capture most of the savings while retaining an agent’s strategic value.

Tall Poppy

Tall Poppy charges a fixed fee of NZ$12,900 to NZ$15,900 including GST for a full-service agent experience—marketing, open homes, negotiation, and settlement support. They do not charge a percentage commission. On a NZ$900,000 sale, that saves NZ$12,000 to NZ$20,000 compared to a traditional agent. Verified at tallpoppy.co.nz. Tall Poppy operates in most New Zealand regions and lists on all major portals.

Arizto

Arizto charges 1.95% + GST of the sale price, with a minimum fee of NZ$4,995. On a NZ$900,000 sale, that is NZ$17,550 + GST = NZ$20,183. The seller handles some open homes and buyer contact, while Arizto provides listing management, photography, and negotiation support. Verified at arizto.co.nz. Good for sellers who want professional pricing guidance but are comfortable doing a portion of the legwork.

List Once

List Once charges a flat fee of NZ$2,490 + GST (NZ$2,862) for a three-month listing across Trade Me, realestate.co.nz, and Homes.co.nz. They provide a professional floor plan, photography, and a dedicated agent to handle offers and negotiations. This is a DIY platform with light agent support. Verified at listonce.co.nz. Best for sellers who are confident in pricing and negotiation but want the marketing reach of an agent’s listing network.

Property Brokers (Fixed Fee Option)

Property Brokers, a traditional agency, offers a “Fixed Fee” service in some regions. The fee is typically around NZ$14,900 plus GST for a full campaign, but this varies by area and property value. Not widely advertised; you must request a quote. This option is worth investigating if you want a major brand with a flat fee.

Cost Comparison: NZ$900,000 Sale

Method Total Cost to Seller Net Proceeds Support Level
Full-service agent (3% + GST) NZ$31,050 NZ$868,950 Full – everything
Tall Poppy (fixed fee) NZ$15,900 NZ$884,100 Full – agent handles all
Arizto (1.95% + GST) NZ$20,183 NZ$879,817 Partial – you do some open homes
List Once (flat fee) NZ$2,862 NZ$897,138 Light – DIY with agent support
Private sale (Trade Me + photos + lawyer) NZ$1,500–NZ$2,500 NZ$897,500–NZ$898,500 None – you do everything

Note: these figures exclude marketing contributions that some agents charge separately (typically NZ$500–NZ$2,000). Always request a full breakdown before signing.

The Decision Rule

If you have a clear buyer in mind, are comfortable setting a price from public sales data, and know the sale process well enough to spot a weak offer, sell privately. The savings are large and the risk is manageable.

If you need a buyer to be found, convinced, and pushed through to settlement—the normal situation—use an agent or a hybrid provider. The smaller net return after commission is the price of reducing the chance of a bad outcome. Most sellers are better off paying that price.

For sellers with strong negotiating skills and flexible schedules, Arizto or List Once offer a good middle ground. For those who want full service but hate the uncertainty of a percentage commission, Tall Poppy’s fixed fee is the safest bet. Buyers rarely discount their offer against a fixed-fee agent because the seller isn’t pocketing a windfall—the agent is paid a set price regardless of the final sale.
