Statement of Accounting Policies

For the Year Ending 30 June 2007

Reporting Entity

The Department of Corrections is a government department as defi ned by section 2 of the Public Finance Act 1989.

These are the financial statements of the Department of Corrections prepared pursuant to section 35 of the Public Finance Act1989 (as if that section had not been amended by the Public Finance Amendment Act 2004) and in accordance with section 33of the Public Finance Amendment Act 2004.

The Department has reported the Crown activities and trust monies that it administers.

Reporting Period

The reporting period covers the 12 months from 1 July 2006 to 30 June 2007. Comparative projected figures for the year ended 30 June 2006 are provided.

Measurement System

These financial statements have been prepared on an historical cost basis modified by the revaluation of certain non-currentassets.

Accounting Policies

The following particular accounting policies, which materially affect the measurement of financial results and financial position, have been applied.


The Department derives revenue through the provision of outputs to the Crown and from the sale of goods and services to third parties. Such revenue is recognised when earned and is reported in the fi nancial period to which it relates.

Cost Allocation

Salaries and related costs of service delivery divisions are charged to outputs on the basis of activity analysis. Activities that are directly related to individual outputs are regarded as direct costs and charged accordingly.

All other costs of service delivery divisions and total costs of support groups are regarded as indirect costs to outputs and are allocated to outputs on the basis of measurement of resource consumption or activity analysis.

Debtors and Receivables

Receivables are recorded at estimated realisable value, after providing for doubtful and uncollectible debts.

Operating Leases

Leases where the lessor effectively retains substantially all the risks and benefits of ownership of the leased items are classified as operating leases. Operating lease expenses are recognised on a systematic basis over the period of the lease.

Physical Assets

Land and buildings are stated at fair value as determined by an independent registered valuer. Fair value is determined using market-based evidence, except for prison buildings, which are valued at optimised depreciated replacement cost. Land and buildings are revalued at least every three years. Additions between revaluations are recorded at cost.

The three-year cycle is subject to a reasonableness test on an annual basis to ensure it does not result in material differences in fair value.

The results of revaluing land and buildings are credited or debited to the asset revaluation reserve. Where a revaluation would result in a debit balance in the revaluation reserve, the debit balance will be expensed in the Statement of Financial Performance.

Land and buildings were last revalued as at 30 June 2005.

All other physical assets, or groups of assets forming part of a network which are material in aggregate, costing more than $3,000 (GST exclusive) or deemed as valuable and/or attractive are capitalised and recorded at cost. Any write-down of an item to its recoverable amount is recognised in the Statement of Financial Performance.


The tree crop is valued annually at market value on the basis that the Department retains the forests to maturity. The market value is based on a three-year rolling average of prices published by the Ministry of Agriculture and Forestry.

The result of revaluing the tree crop is recognised in the Statement of Financial Performance.


Depreciation is provided on a straight-line basis on all fixed assets, other than freehold land, forestry and items under construction, over their estimated economic useful lives. There is no allowance for residual values, except for 'motor vehicles - other', which have a residual value of 20 percent of cost. Revalued assets are depreciated on their revalued amount on a straight-line basis over their remaining useful lives.

The economic useful lives and associated depreciation rates of classes of assets have been estimated as follows:

Buildings - structure

50 years


Buildings - fit-outs

3 to 20 years

(33.3 to 5%)

Hut complexes

25 years


Hut fit-outs 

3 to 20 years

(33.3 to 5%)

Leasehold improvements

10 years


Plant and machinery

10 years


Office equipment

5 years


Tools and equipment

5 years


Furniture and fittings - office

5 years


Furniture and fittings - prisoner

3 years


Information technology - network

5 years


Information technology - specialised

3 to 10 years

(33.3 % to 10%)

Information technology - PC based

3 years


Motor vehicles - heavy duty

8 years


Motor vehicles - other

5 years


The useful life of buildings is reassessed following any revaluation.

Where the fixed term of a lease is for less than 10 years, excluding rights of renewal, the useful life for leasehold improvements is set at that lesser period.


Finished goods, raw materials and work in progress are valued at the lower of cost or net realisable value. Costs have been assigned to inventory quantities on hand at balance date using the first-in first-out basis for finished goods and work in progress, and the weighted-average basis for raw materials. Cost comprises direct material and direct labour together with an appropriate portion of fixed and variable production overheads.

Employee Entitlements

Provision is made in respect of the Department’s liability for annual, long service and retirement leave. Annual leave is measured at nominal values on an actual entitlement basis at current rates of pay.

Entitlements that are payable beyond 12 months, such as long service leave and retirement leave, have been calculated on an actuarial basis based on the present value of expected future entitlements.

Statement of Cash Flows

Cash means cash balances on hand and held in bank accounts.

Operating activities include cash received from all income sources of the Department and record the cash payments made for the supply of goods and services.

Investing activities are those activities relating to the acquisition and disposal of non-current assets.

Financing activities comprise capital injections by, or repayment of capital to, the Crown.


Livestock is valued annually using Inland Revenue’s national average market value. Gains due to changes in the per head value of the livestock herd at balance date are taken to the revaluation reserve. Losses due to changes in the per-head value are applied against the revaluation reserve to the extent that there are sufficient reserves, otherwise they are taken to the Statement of Financial Performance. Gains and losses due to changes in livestock numbers are taken directly to the Statement of Financial Performance.


Investments are valued at the lower of cost or net realisable value. Investments arise from the Department's dealings with companies in the farming industry.

Foreign Currency

Foreign currency transactions are converted into New Zealand dollars at the exchange rate at the date of the transaction.

Financial Instruments

The Department is party to financial instruments as part of its normal operations. These financial instruments include bank accounts, debtors and creditors. All fi nancial instruments are recognised in the Statement of Financial Position and all revenues and expenses in relation to fi nancial instruments are recognised in the Statement of Financial Performance.

Except for those items covered by a separate accounting policy, all fi nancial instruments are shown at their estimated fair value.

Goods and Services Tax (GST)

The Statement of Financial Position is exclusive of GST except for Creditors and Payables and Debtors and Receivables, which are GST inclusive. All other statements are GST exclusive.

The amount of GST owing to the Inland Revenue Department at balance date, being the difference between Output GST and Input GST, is included in Creditors and Payables.


Government departments are exempt from the payment of income tax in terms of the Income Tax Act 1994. Accordingly, no charge for income tax has been provided for.


Future expenses and liabilities to be incurred on capital and operating contracts that have been entered into at balance date are disclosed as commitments to the extent that there are equally unperformed obligations. Commitments relating to employment contracts are not disclosed.

Contingent Liabilities

Contingent liabilities are disclosed at the point at which the contingency is evident.

Taxpayers' Funds

This is the Crown’s net investment in the Department.

Changes in Accounting Policies

There have been no changes in accounting policies, including cost allocation accounting policies, since the date of the last audited financial statements.

All policies have been applied on a basis consistent with the previous year.
