⁽¹⁾ Detailed height restriction diagrams for Kaipara Flats Airfield, North Shore Airfield and Parakai Airfield are contained in this overlay section of the Unitary Plan. Auckland International Airport (AIA), Whenuapai Airbase and Ardmore Aerodrome diagrams are contained in the designation overlay section of the Unitary Plan.

1. Buildings, structures, masts and trees must not exceed the height limit within the obstacle limitation surfaces in accordance with Figures 2 - 4.
a. At any point where two surfaces overlap and are at differing elevations, the lower of the two surfaces must apply.
b. Detailed height restrictions for Kaipara Flats Airfield, North Shore Airfield and Parakai Airfield are contained in Appendix 2.1.
c. No part of any building or any tree must exceed a height equal to 8 metres, provided that any building or tree must not exceed the height limits specified in Figures 2 - 4 and detailed height restriction diagrams contained in Appendix 2.1.

2. The height restrictions consist of three separate height controls around North Shore Airfield and two around Kaipara Flats and Parakai Airfields. (Refer to Figures 2 - 4)
a. Take off/landing fans:
These fans extend for 5.5km (north Shore) and 1.2km (Kaipara Flats and Parakai) from each end of each runway. The height limit begins at ground level and rises at a slope of 1 in 40 (North Shore) and 1 in 20 (Kaipara Flats and Parakai).
b. Transitional side surfaces:
This height restriction runs at right angles to the runway strip and the centre line of the fans. The height limit begins at ground level at the edge of runway strip and rises at a slope of 1 in 7 (North Shore) and 1 in 4 (Kaipara Flats and Parakai) to a maximum height of 45 metres (North Shore) and 2 metres (Kaipara Flats and Parakai) above the runway ground level. This height limit also applies from the outside edge of each fan, the surface rising at the same slopes to a maximum height of 45 metres (North Shore) and 2 metres (Kaipara Flats and Parakai).
c. Horizontal surface:
All properties within 2.6km of North Shore Airfield are subject to a horizontal height control which is 45 metres above the average runway ground level i.e. 107 metres above mean sea level. There is no horizontal surface control for either Kaipara Flats or Parakai Airfields.

3. All height restrictions are affected by the elevation of the property, and height limits must be assessed in terms of elevation relative to the runway it self.

The following table below gives the specifications for the three airfields:

1. The airport authority must, if so required by the owners of the affected dwellings defined in clause 4.4.1.2.3.2.2.b below, pay for any remedial or supplementary works considered necessary to ensure the internal acoustic environment of habitable rooms in those dwellings does not exceed a maximum of Ldn 40 dBA with all external doors and windows closed, as the result of aircraft movements represented in the Air Noise Boundary noise contour as shown on District Plan Maps.

2. Where compliance with the design level relies on doors and windows being closed, alternative approved mechanical ventilation in accordance with the Building Code must be provided, subject to the following:
a. Notice of such requirement must be given in writing to the registered office of the airport authority within three months of the owners receiving written notice from the airport authority advising them of the operative date of this rule and the rights conferred by this rule.
b. The affected dwellings are deemed to be those existing habitable dwellings located within the Ldn 65dBA Air Noise Boundary contour as at 19 September 2001. Where any existing habitable dwelling is in the course of completion, extension or repair as at 19 September 2001, notice to the airport authority referred to above must be given within three months following the date on which the dwelling is certified as complete by the council pursuant to the Building Act 2004, or the date of written notice from the airport authority advising the owners of the operative date of this rule, whichever is the later.
c. Suitably qualified and experienced persons appointed by the airport authority and the council will act as the certifiers in determining the nature and extent of the remedial or supplementary works required pursuant to this rule and their determination will bind the airport authority, the council and the owners respectively in relation to their various interests pursuant to this rule.

3. Subject to the rules above, the obligations of the airport authority under this rule will not extend to any subsequent structures, alterations or additions to any of the affected dwellings commenced after 19 September 2001.

1.  Opening windows are allowed in ASAN and additions and alterations to an existing ASAN of habitable rooms and rooms for sleeping, convalescing and learning in the ANB, ICB and OCB.

2.  Where non-opening windows are used in ASAN and additions and alterations to an existing ASAN of habitable rooms and rooms for sleeping, convalescing and learning in the ANB, ICB and OCB, an early warning smoke detection system must be installed and maintained within the premises, including in rooms for sleeping and exit ways, in accordance with an approved New Zealand Code or Standard or AS3786:1993. Where mechanical ventilation is provided, devices must be installed to shut down or close off the system to prevent the travel of fire and smoke products.

1. A post-construction demonstration of compliance with the sound attenuation required in Part 4.4.1.2.3.1 - Acoustic insulation and ventilation, is a condition of occupancy of ASAN in the ANB, ICB and OCB and must be provided to council prior to occupancy. Compliance with the sound attenuation clause 2.2.1.1 must be achieved in the absence of any absorptive surface finishes, such as carpeting or furnishings. This performance standard will be required for each room within the residential building that is typically occupied, such as bedrooms, living rooms, dining rooms and dens. All building systems should be off during the testing to minimise background noise, including appliances and forced-air ventilation systems.

2. The post-construction performance test must be conducted in accordance with ASTM E966–04 Standard Guide for Field Measurements of Airborne Sound Insulation of Building Facades and Façade Elements to obtain proportionate bandwidth spectra, such as octave band, for the exterior and interior locations based on actual aircraft events with appropriate corrections for background noise. The term outdoor-indoor level reduction (OILR) is equivalent to the term 'noise reduction' in these rules. The exterior microphone must be situated at least 2m from reflective exterior surfaces and situated as far as possible from such surfaces to obtain a representative outdoor noise level for the residence under test.

3. The noise reduction obtained via this test standard and the approaches described above will be 'normalised' with regard to a representative spectrum for aircraft operations from Ardmore Aerodrome and not restricted to the results obtained for a limited number of aircraft events.

Train	+5dB	+6dB	-2dB	-3dB	-4dB	-9dB	-15dB

3. Except where noise measurements demonstrate otherwise, in determining compliance with clause 4.4.1.5.2.1, train noise will be deemed to be 72dB LAeq(1 hour) at a distance of 12m from the edge of the rail line for the purpose of compliance with the maximum internal noise levels in Table 1 and will be deemed to drop off at a rate of 3dB per doubling of distance up to 40m. The noise measurements will be made at a position representative of 1m from the most exposed façade of the building or room to be constructed and must assume that four freight trains per hour will go past that measurement point.

4. In determining compliance with clause 4.4.1.5.2.1 traffic noise will be based on a one-hour measurement of the external sound level, on a weekday between 2pm and 6pm during school term-time, at a position representative of 1m from the most exposed part of the building or room to be constructed. Noise levels must be measured under free flow traffic conditions. dB will be added to the measured level to account for possible increases in the number or type of motor vehicles and 2dB to account for possible increases in the number, type or length of trains likely to use that road or rail line in the next 10 years.

1. Where a new room or rooms that are additions or alterations of an existing building and increase the GFA of the building by no more than 10 per cent, those rooms must meet the ventilation requirements of the Building Code (G4) at the same time as they meet the controls in Table 1.

2. Where a new building is constructed with rooms subject to clause 4.4.1.5.2.1 or where a new room or rooms that are included in Table 1 are additions or alterations of an existing building increase the GFA of that building by more than 10 per cent the rooms must be provided with:
