Kia ora Dan,
I am wri�ng with reference to your request to the CAA under the Official Informa�on Act for the
following informa�on (CAA Reference
24/OIR/268) –
I would like to request the fol owing information about CAA's protocol around runway
numbering/designations:
1. How often are runway numbers reviewed in response to changes in magnetic north?
2. Is this review the responsibility of CAA or each individual aerodrome operator?
3. Which aerodromes have changed their runway numbers in the last 10 years?
4. Does the CAA publish runway number changes publicly when they occur? If so, where? (other than
the aerodrome charts themselves on AIP being updated)
Decision
1. How often are runway numbers reviewed in response to changes in magnetic north?
Aeronau�cal data, specific to magne�c north changes, wil be reviewed as a minimum every
5 years as part of the obstacle limita�ons surface (OLS) surveys conducted by a registered
surveyor on behalf of the aerodrome operator.
2. Is this review the responsibility of CAA or each individual aerodrome operator?
It is the aerodrome operator’s responsibility to ensure all aeronau�cal informa�on is current
and accurate.
3. Which aerodromes have changed their runway numbers in the last 10 years?
As far as the Authority is aware, no runway numbers have changed in New Zealand in the last
10 years at Part 139 cer�ficated airports.
4. Does the CAA publish runway number changes publicly when they occur? If so, where?
(other than the aerodrome charts themselves on AIP being updated)
The AIP Supplement would be used, possibly NOTAM as well as the airport’s own
communica�on channels. As changes to runway numbers will be infrequent any change
could also make for an interes�ng CAA ar�cle, either on our website, in the CAA Briefing
Newsleter which is sent to avia�on par�cipants up to four �mes a year, or via the CAA
Vector magazine.
