System overview
About ESASESAS is New Zealand’s principal high-value payments system which is used to settle payment instructions
between accountholders. The system is charged with providing an efficient and safe process for the real time
electronic settlement of payments between accountholders.
The Reserve Bank has provided ESAS as a real-time gross settlement system since 1998.
Accountholders electronically submit instructions to debit an account and credit another account using an
authorised electronic submitting mechanism. Authorised submitting mechanisms include closed user groups
which utilise the SWIFT electronic messaging system, the NZClear system and direct entry of transaction
details to ESAS. The system is available for use by accountholders for 23.5 hours each business day. Each
business day commences at 9.00am on a working day and ends at 8.30am the following working day.
A payment will be settled (i.e. funds are transferred from one ESAS accountholder’s exchange settlement
account to another ESAS accountholder’s exchange settlement account) once a transaction instruction is
authenticated, the payment instruction is authorised by the payer and the payer has sufficient funds in their
exchange settlement account to effect the transaction. Once a transaction is settled it cannot be revoked.
The ESAS system is operated by the Reserve Bank. The Reserve Bank’s Financial Services Group
(“FSG”) is responsible for the administration of the operational aspects of the system. FSG is headed by
Mike Wolyncewicz, the Reserve Bank’s Chief Financial Officer, and day-to-day business support is provided
by the Payment and Settlement Services Team within FSG that is managed by the Manager of Payments
and Settlement Services, Nathan Lewer.
FSG reports on the operation of ESAS to Geoff Bascand, Deputy Governor and Head of Operations.
The Reserve Bank’s Knowledge Services Group (“KSG”) supports the telecommunications network and
related security features utilised by the system. Software support, software development and operational
support services are provided by Datacom Systems (Wellington) Limited (“Datacom”).
The aggregate level of liquidity in the ESAS system is managed by the Reserve Bank’s Financial Markets
Department (“FMD”). FMD injects or withdraws liquidity from the system by undertaking transactions such as
reverse repurchase agreements, foreign currency swap transactions, and issuance of Reserve Bank Bills.
FMD’s objective is to ensure that there is adequate aggregate liquidity in the system to ensure the efficient
operation of payment operations while also maintaining short-term wholesale interest rates at levels close
to the Official Cash Rate. Typically aggregate system liquidity is maintained in the range of $7 billion to $9
billion.
ESAS is a designated settlement system under Part 5C of the Reserve Bank Act 1989. The regulator
is the Prudential Supervision Department of the Reserve Bank. Institutional arrangements are in place to
ensure that dealings between the Financial Services Group and the Prudential Supervision Department
occur on an arm’s length basis.

Management commentary
Year ended 30 June 2015Key performance statistics are:
Key performance indicator 2015 2014
• System availability (%) 99.87 99.78
• Average daily transactions 11,332 10,443
• Revenue ($000) 4,038 3,162
Customer satisfaction - meets
or exceeds expectations (%) 100 100
Finance and operationsESAS is operated on a cost recovery basis. Expenditure and therefore charges to accountholders
increased largely as a result of project costs associated with the strategic review of the Bank’s settlement
operations including the proposed replacement of ESAS, and also additional amortisation charges due to a
reassessment of the useful life of system software in light of the proposed replacement of ESAS.
The Bank continues to maintain the system, and as indicated in business plans in recent years, there
is a limited programme for developing system functionality. An important development this year was the
successful delivery of a replacement interface between both ESAS and NZClear systems and the SWIFT
network. This was a significant project undertaken to replace software which was deployed in 2001 and
which the vendor advised would no longer be supported. The capital cost of this project is being amortised
over a relatively short period of three years, and has contributed to the increase in operating costs.
The system was available to users 99.87% of core hours. This measure does not differentiate matters
beyond the Bank’s control such as internet outages and availability was 99.91% excluding matters beyond
the Bank’s control. The Bank aims to deliver the system with 99.90% availability.
The Bank has prepared a draft assessment of ESAS’s compliance with the principles for Financial
Market Infrastructures. The Bank is considering the regulator’s feedback on that draft and plans to publish
the self-assessment in September 2015.Arch

Strategic DevelopmentsDuring 2014/15, the Bank completed its strategic review of its payment operations activities and reported
back to stakeholders. This included stating the Bank’s vision, principles, and core requirements for operations
that the Bank is responsible for.
One of the key findings of the review is that providing securities settlement and depository services
is not a core central bank function. Additionally, the Bank’s payment and settlement systems, ESAS and
NZClear, will require significant investment or replacement over the next several years. Therefore the Bank
has decided to replace ESAS and to divest the NZClear business if another specialist operator can provide
securities settlement and depository services that meet both the Bank’s operational requirements and users’
needs.
The search for a new system to replace ESAS is well advanced. Accountholders will be kept apprised of
progress and the Bank will ensure members have the opportunity to comment on the planned procurement
before a decision is made.

Key statistics
Transactions – All
There are three primary interfaces or “Accountholder Submitting Systems” which are used by ESAS
Accountholders to submit payment instructions to ESAS:
• directly from the NZClear system.
• via the SWIFT system where members of the Assured Value Payment “AVP” closed user group use
ESAS to pay other members of that closed user group. The Reserve Bank is the administrator of the AVP
closed user group.
• via the SWIFT system where members of the Settlement Before Interchange “SBI” closed user group
use ESAS to pay other members of that closed user group. Payments NZ Limited is the administrator of
the SBI closed user group. Once an SBI settlement has been effected in ESAS, a confirmation is sent
to SWIFT which then allows an associated interchange file containing underlying payment details to be
released to the destination bank.
• There is steady growth in the volume of
transactions submitted to ESAS. After several
years of subdued growth post the global financial
crisis, average daily values of transactions
increased quite markedly from $25.9 billion to
$29.3 billion.
Transactions – Sourced from SWIFT “AVP”
• Transactions submitted to ESAS via the main
SWIFT closed user group known as “AVP”
dominate overall ESAS activity, both in terms
of volumes and values. Transaction numbers
are growing at a steady rate and the average
daily value of AVP transactions appear to also
be increasing.

System outages year ended 30 June (hours: mins) • The system was available 99.87% during
core support hours (2014: 99.78%).
• There were two main outages totalling
306 minutes, but due to affecting a
subset of users only, the business impact
of these incidents was very limited as
alternate processing methods were able
to continue. All incidents are followed up
through post-incident analysis in order to
minimise the chance of recurrence.Customer satisfaction
• The 2015 annual customer satisfaction
survey showed that customer satisfaction
remains at a high level.
• Members provided feedback on the
limited system flexibility and complexity
of development.

• The SBI interface to ESAS commenced
operation in February 2012. Volumes are
growing steadily as banks submit more files to
ESAS during the banking day.
• Transactions sourced from the NZClear system
reflect high NZClear turnover in recent years
which results from high activity on the New
Zealand share market.

Risk management
The internal controls of the ESAS system are audited each year by PricewaterhouseCoopers (“PwC”), as
required by the ESAS Terms and Conditions. PwC act on behalf of the Reserve Bank’s external auditor, the
Auditor-General. The scope of this audit includes the controls performed by the Reserve Bank’s third party
independent service provider, Datacom. The Auditor’s annual assurance report is addressed to the Governor
of the Reserve Bank and is reviewed by the Reserve Bank’s Audit Committee, with external auditors, Reserve
Bank governors and management in attendance. A copy of the assurance report is sent to accountholders,
and is published on the Bank’s website.
ESAS is also subject to internal audit by the Reserve Bank’s Audit Services division.
The main elements of risk management for the System entail:
• procedures and controls are adhered to;
• measures to manage operational risk, as described below;
• business continuity plans are in place and tested regularly; and
• ongoing oversight and audit of operations.
Managing operational risk in the Reserve Bank is seen as an integral part of day-to-day operations.
Operational risk management includes Bank-wide corporate policies that describe the standard of conduct
required of staff, a number of mandated requirements (e.g. a project management template), and specific
internal control systems designed around the particular characteristics of various Reserve Bank activities.
The Reserve Bank has a small office in Auckland. As a result, day-to-day operating activities are shared
between staff based in Auckland and those based in Wellington. Staff in the Auckland office will provide
on-going continuity of business operations should a region-wide disaster impact ESAS’s Wellington staff. A
second computer site is located in Auckland and is used alternately with the Wellington computers for live
production.

Financial performance
A short-form Statement of Financial Performance for the ESAS business is:
2015 2014
$000 $000
Revenue 4,038 3,162
Expenses 4,002 3,128
Net profit 36 34
As noted above, the Bank incurred higher costs in respect of the ESAS system due to higher amortisation
charges and also costs associated with the Payment Systems Replacement project. The current system is
complex and is nearing the end of its economic life. The majority of expenditure is incurred on system support
required to maintain the software, ensuring it continues to operate at the high level of availability and security.
The ESAS business is attributed costs by the Reserve Bank. This includes charges for use of the
Reserve Bank’s resources, such as staff, occupancy, internal audit, governance, accounting and information
technology. Indirect costs incurred by the Reserve Bank are allocated to the ESAS System based on
estimated costs that the business would incur on a stand-alone basis.
The ESAS business is operated as a division of the Reserve Bank. The above figures are extracted from
the Reserve Bank’s audited financial statements, but the accounts of this division have not been subject to a
separate external audit. Income and expenditure for the ESAS business is calculated using the accounting
policies specified in the Reserve Bank’s financial statements.
Under the ESAS terms and conditions, the Bank may only recover the costs of operating the system. The
small net profit recorded reflects project costs related to the SBI development which were expensed in earlier
years for financial reporting but which are being recovered via fees charged over 5 years.Archive
