The New Zealand Crown has always paid when due the full amount of principal, interest and amortisation requirements upon its external and internal debt, including guaranteed debt.
During 1988, as part of the reform of the Government’s financial management, the New Zealand Debt Management Office (NZDMO) was formed as an operational unit of the Treasury. It is responsible for the efficient management of the Crown’s debt and associated financial assets within an appropriate risk management framework. Its broader responsibilities include providing capital market advice and financial transaction services to other agencies of the Crown.
New Zealand Government Securities
The Treasury’s NZDMO manages the issuance of nominal bonds, inflation-indexed bonds (IIBs) and Treasury Bills (T-Bills) in the wholesale market. At 30 April 2018 there were NZD 77.7 billion of bonds on issue. Of these, NZD 74.4 billion were market bonds that may be freely traded in the secondary market. In addition, there were NZD 4.1 billion of T-Bills on issue.
Over the forecast period, total outstanding bonds are projected to remain above NZD 70 billion. The Government’s recent commitment to maintain NZGBs on issue at not less than 20% of GDP over time ensures long-term durability of the NZGB market, even if net core Crown debt were to fall below 20% of GDP.
At 31 May 2018 there were nine nominal bond and four IIB maturities as shown in Chart 5. Individual nominal bond maturities are capped at NZD 12 billion outstanding, while IIB maturities are capped at NZD 6 billion. Coupons on nominal bonds are paid on a semi-annual basis, in arrears. For IIBs, coupons are paid quarterly.

New Zealand’s credit rating is within the top twenty sovereign ratings globally. Rating agencies Standard & Poor’s and Fitch currently maintain an AA long-term foreign currency rating for NZGBs. Moody’s has maintained an Aaa long-term foreign currency rating on the bonds since October 2002.

Primary issuance of New Zealand Government Securities is undertaken through competitive tenders and/or syndications.
The BEFU and HYEFU announcements contain a breakdown of the Crown’s funding needs and annual bond issuance forecasts. The most recent update, published alongside BEFU in May 2018, is shown in Table 3.
Ahead of each quarter, the Treasury’s NZDMO pre-announces a regular bond issuance schedule. Approximately two weeks prior to the end of the quarter (around the time of the last tender of that quarter) the NZD value, and maturity of bonds to be issued on specified dates in the subsequent quarter, are announced.
NZGB tenders are typically held on Thursdays. Interested parties may offer their bids through a registered tender counterparty. Bids must be submitted by 2pm on the day of tender. The minimum denomination is NZD 1 million (principal) and in multiples of NZD 1 million thereafter.
T-Bills are also issued via tender. These occur fortnightly, on Tuesdays, when bids need to be submitted by 2pm. Typically 3 month, 6 month and 12 month maturities are offered. The volume and maturities on offer may vary and are announced the day prior to tender.
Syndication has historically been confined to launching a new bond. This method enables the placement of a large volume into the market, promoting liquidity in the new bond from initiation. Recent syndication volumes have been between NZD 1.5-2.0 billion.
NZGB yields generally trade some way above global developed market peers. Over the past two decades generic 10-year NZGBs have traded between -30bps and 300bps relative to their US equivalents. Over the same period they have traded between -40bps and 140bps over Australian equivalents.
In terms of absolute levels, NZGB yields have been on a declining trend in recent decades, in line with the global disinflationary trend. Specifically in New Zealand, the RBNZ Act of 1989 entrenched an inflation-targeting mandate. This has contributed to structurally lower yields as inflation expectations have declined.
The secondary market is supported by major local banks and global intermediaries. There is a repurchase market for NZGBs. The RBNZ publishes data showing weekly and monthly turnover of New Zealand Government Securities.

Considerations for Non-Residents
NZGBs are effectively free from withholding tax for non-resident investors. While NZGBs are subject to an Approved Issuer Levy like other New Zealand bond issues, the Crown will pay this tax on behalf of non-resident investors.
At April 2018, 60% of NZGBs were held by non-resident investors. Over the past fifteen years this percentage has ranged between 50% and 80%. Participants in the market are diverse by type and by regional location. Nominal NZGBs and IIBs are currently constituents of a number of global benchmark bond indices.
New Zealand Government Securities are currently issued only in New Zealand dollars. However, documentation is maintained to enable issuance in alternative currencies.
The Treasury's NZDMO maintains regular contact with its investors via a variety of channels and welcomes enquiries.
