How to buy bonds in New Zealand
There are exactly two routes into the New Zealand bond market: apply directly to the Crown for Kiwi Bonds, or open a sharebroker account for everything listed on the NZX Debt Market. Here is what each involves.
1. Decide which tier of the market you want
Kiwi Bonds are bought directly from the Crown with no broker and a $1,000 minimum. Everything else — government, council, corporate and green bonds — trades on the NZX Debt Market and needs a sharebroker. That single decision determines the whole process.
2. Open a sharebroker account (for listed bonds)
You will need a broker that handles NZX debt securities, plus a CSN or holder number and an FIN. Expect identity verification, an IRD number and a nominated bank account. Setting this up takes a few days, so do it before a new issue you want closes.
3. Choose between a new issue and the secondary market
In a new issue you apply through the broker at the offer terms and pay face value, usually with no brokerage. On the secondary market you buy an existing line at whatever it currently trades for, which is where the difference between coupon and yield to maturity comes from.
4. Check the minimum parcel and the total cost
Most listed New Zealand retail bonds trade from $5,000, with government lines usually from $10,000. On top of the price you pay brokerage, and on a secondary purchase you also pay the seller the interest accrued since the last payment date.
5. Place the order and settle
Bond trades settle on a standard NZX cycle, and the holding appears against your CSN. Interest is paid directly into your nominated bank account, net of resident withholding tax at the rate you have notified.
6. Plan the maturity, not just the purchase
Face value is repaid at maturity, and reinvestment is your problem to solve at whatever rates apply then. Laddering — spreading purchases across several maturity years — is the standard way to avoid rolling your entire portfolio at a single point in the rate cycle.

Brokerage on New Zealand bond trades is typically a percentage of the trade value with a minimum dollar charge, which means small parcels carry a proportionally higher cost. On a $5,000 purchase the minimum brokerage can quietly take a chunk out of your first year's interest.
New issues are usually brokerage-free to the investor because the issuer pays the distribution costs. That is one practical argument for buying at issue rather than on market if a suitable new offer is open.
Interest is taxable income. Resident withholding tax is deducted at your notified rate, and if you have not supplied an IRD number the default rate applied is the highest one — so supply it.
Where most first-time buyers go wrong
Buying on coupon instead of yield. A bond with a 7.25% coupon trading above face value may yield materially less than 7.25% to maturity. The yield is your return; the coupon is just the cash flow.
Assuming listed means liquid. Many New Zealand retail bond lines are small and trade infrequently. Buy on the assumption you will hold to maturity, and treat early exit as a bonus rather than a plan.
Ignoring seniority and call dates. Subordinated notes and capital notes pay more for structural reasons that only matter when things go wrong — which is exactly when you will care.
