Pursuant to sections 401(1) and 412(c) of the Accident Insurance Act 1998, His Excellency the Governor-General, acting by and with the advice and consent of the Executive Council, makes the following regulations.

Regulations

1 Title and commencement
  • (1) These regulations may be cited as the Accident Insurance (Occupational Hearing Assessment Procedures) Regulations 1999.

    (2) These regulations come into force on 1 July 1999.

2 Interpretation
  • In these regulations, unless the context otherwise requires,—

    “A” weighting means the A frequency weighting specified in the International Standard IEC 651—1979

    Act means the Accident Insurance Act 1998

    AS ISO 8253.1 means the Australian Standard: International Organisation for Standardization on Acoustics - Audiometric Test Methods, Part 1: Basic Pure Tone Air and Bone Conduction Threshold on Audiometry: AS ISO 8253.1-2009

    decibel is a dimensionless unit used to compare the magnitudes of powers, intensities, or pressure squared

    degree of deafness means the binaural percentage loss of hearing as a result of a hearing impairment as determined using the tables set out in Schedule 1

    gradual process hearing test means the test used to assess a claim for deafness arising from a personal injury caused by a work-related gradual process as required for the purposes of section 61 of the Accident Compensation Act 2001

    HTL means the hearing threshold level

    Hz, which is the international measure of frequency, means hertz where 1 hertz equals 1 cycle per second

    insurer means an insurer within the meaning of section 75 of the Act

    Leq (8) means that steady noise level measured in A-weighted decibels referenced to 20 micropascals that, when present for 8 hours, causes the same A-weighted noise energy to be received as that due to the actual noise over the actual working day

    otolaryngologist means a medical practitioner—

    • (a) whose scope of practice includes—

      • (i) the branch of medicine of otolaryngology head and neck surgery; or

      • (ii) a branch of medicine that is determined by the Medical Council to be equivalent to the branch of medicine of otolaryngology head and neck surgery; and

    • (b) who is, in performing any function under these regulations, practising within that branch of medicine; and

    • (c) who is, in performing any function under these regulations, practising in accordance with any conditions included, or deemed to be included, in his or her scope of practice, including any conditions imposed by any order made under section 101 of the Health Practitioners Competence Assurance Act 2003 or section 110 of the Medical Practitioners Act 1995 or section 58 of the Medical Practitioners Act 1968; and

    • (d) who is, if 1 or more conditions of the kind referred to in paragraph (c) apply to the medical practitioner, a suitable person, in the opinion of the insurer, to perform any function required or permitted by these regulations to be performed by an otolaryngologist

    presbyacusis means the gradual loss of hearing that can be attributed to the ageing process

    scope of practice has the same meaning as in section 5(1) of the Health Practitioners Competence Assurance Act 2003

    worse ear means the ear with the greater HTL at the relevant audiometric frequency.

    Regulation 2 AS ISO 8253.1: inserted, on 1 January 2012, by regulation 4(2) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 2 base-line hearing test: revoked, on 1 January 2011, by regulation 4(4) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 2 gradual process hearing test: amended, on 1 January 2011, by regulation 4(5) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 2 ISO 6189: revoked, on 1 January 2012, by regulation 4(6) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 2 otolaryngologist: substituted, on 18 September 2004, by section 175(3) of the Health Practitioners Competence Assurance Act 2003 (2003 No 48).

    Regulation 2 scope of practice: inserted, on 18 September 2004, by section 175(3) of the Health Practitioners Competence Assurance Act 2003 (2003 No 48).

3 Application
  • These regulations apply to a claimant who is required to undergo a gradual process hearing test.

    Regulation 3: substituted, on 1 January 2011, by regulation 5 of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

4 Procedures to be followed in assessment
  • (1) The claimant must undergo a pure tone audiometry test of binaural loss of hearing conducted by an otolaryngologist or audiologist.

    (2) A test of the hearing of any claimant must be diregarded if the claimant has been exposed to a noise level that is likely to result in a temporary threshold shift being present during the test (such as the Leq (8) hour level greater than 85 dBA within 16 hours before testing); and the person conducting the test must ask the appropriate questions to determine whether any such exposure has occurred.

    (3) During each test, the air conduction HTL of the insured must be measured with an audiometer at audiometric frequencies 500, 1 000, 1 500, 2 000, 3 000, 4 000, 6 000, and 8 000 Hz.

    (4) During each test, the HTL of both the better ear and the worse ear must be measured at each audiometric test frequency.

    (5) The binaural percentage loss of hearing at each audiometric frequency must be calculated in accordance with the tables set out in Schedule 1 using the HTL of the better ear and the worse ear as co-ordinates.

    (6) The percentage loss of hearing calculated at each of the 8 audiometric frequencies is added together to obtain the overall percentage loss of hearing.

    (7) Every pure tone audiometry test undertaken under these regulations must comply with the technical and procedural standards of AS ISO 8253.1.

    Regulation 4(1): amended, on 1 January 2011, by regulation 6(1) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 4(2): amended, on 1 January 2011, by regulation 6(2) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

    Regulation 4(7): amended, on 1 January 2012, by regulation 6(3) of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

5 Adjustment for hearing loss due to presbyacusis
  • For a gradual process hearing test, the overall percentage loss of hearing calculated under regulation 4(6) must be adjusted for presbyacusis by reducing the overall percentage loss of hearing by the appropriate percentage specified in Schedule 2.

    Regulation 5: amended, on 1 January 2011, by regulation 7 of the Accident Insurance (Occupational Hearing Assessment Procedures) Amendment Regulations 2010 (SR 2010/425).

6 Report of assessment
  • In making a report of an assessment of degree of deafness, the otolaryngologist or audiologist must specify—

    • (a) the tests undertaken; and

    • (b) the results of these tests; and

    • (c) the make and model of the audiometer used in those tests; and

    • (d) the date of the last basic calibration of the audiometer and the name of the laboratory that conducted the calibration; and

    • (e) the age of the claimant, and whether an adjustment has been made under regulation 5; and

    • (f) any other comments relevant to the assessment.

7 Revocations
  • The following regulations are consequentially revoked:

    • (a) Accident Rehabilitation and Compensation Insurance (Occupational Deafness Assessment Procedures) Regulations 1992 (SR 1992/223):

    • (b) Accident Rehabilitation and Compensation Insurance (Occupational Deafness Assessment Procedures) Regulations 1992, Amendment No 1 (SR 1996/299).

Notes
1 General
  • This is a reprint of the Accident Insurance (Occupational Hearing Assessment Procedures) Regulations 1999. The reprint incorporates all the amendments to the regulations as at 1 January 2012, as specified in the list of amendments at the end of these notes.

    Relevant provisions of any amending enactments that contain transitional, savings, or application provisions that cannot be compiled in the reprint are also included, after the principal enactment, in chronological order. For more information, see http://www.pco.parliament.govt.nz/reprints/ .

2 Status of reprints
  • Under section 16D of the Acts and Regulations Publication Act 1989, reprints are presumed to correctly state, as at the date of the reprint, the law enacted by the principal enactment and by the amendments to that enactment. This presumption applies even though editorial changes authorised by section 17C of the Acts and Regulations Publication Act 1989 have been made in the reprint.

    This presumption may be rebutted by producing the official volumes of statutes or statutory regulations in which the principal enactment and its amendments are contained.

3 How reprints are prepared
  • A number of editorial conventions are followed in the preparation of reprints. For example, the enacting words are not included in Acts, and provisions that are repealed or revoked are omitted. For a detailed list of the editorial conventions, see http://www.pco.parliament.govt.nz/editorial-conventions/ or Part 8 of the Tables of New Zealand Acts and Ordinances and Statutory Regulations and Deemed Regulations in Force.

4 Changes made under section 17C of the Acts and Regulations Publication Act 1989
  • Section 17C of the Acts and Regulations Publication Act 1989 authorises the making of editorial changes in a reprint as set out in sections 17D and 17E of that Act so that, to the extent permitted, the format and style of the reprinted enactment is consistent with current legislative drafting practice. Changes that would alter the effect of the legislation are not permitted.

    A new format of legislation was introduced on 1 January 2000. Changes to legislative drafting style have also been made since 1997, and are ongoing. To the extent permitted by section 17C of the Acts and Regulations Publication Act 1989, all legislation reprinted after 1 January 2000 is in the new format for legislation and reflects current drafting practice at the time of the reprint.

    In outline, the editorial changes made in reprints under the authority of section 17C of the Acts and Regulations Publication Act 1989 are set out below, and they have been applied, where relevant, in the preparation of this reprint:

    • omission of unnecessary referential words (such as of this section and of this Act)

    • typeface and type size (Times Roman, generally in 11.5 point)

    • layout of provisions, including:

      • indentation

      • position of section headings (eg, the number and heading now appear above the section)

    • format of definitions (eg, the defined term now appears in bold type, without quotation marks)

    • format of dates (eg, a date formerly expressed as the 1st day of January 1999 is now expressed as 1 January 1999)

    • position of the date of assent (it now appears on the front page of each Act)

    • punctuation (eg, colons are not used after definitions)

    • Parts numbered with roman numerals are replaced with arabic numerals, and all cross-references are changed accordingly

    • case and appearance of letters and words, including:

      • format of headings (eg, headings where each word formerly appeared with an initial capital letter followed by small capital letters are amended so that the heading appears in bold, with only the first word (and any proper nouns) appearing with an initial capital letter)

      • small capital letters in section and subsection references are now capital letters

    • schedules are renumbered (eg, Schedule 1 replaces First Schedule), and all cross-references are changed accordingly

    • running heads (the information that appears at the top of each page)

    • format of two-column schedules of consequential amendments, and schedules of repeals (eg, they are rearranged into alphabetical order, rather than chronological).
