ARENA - previously known as NANAC

ARENA’s community noise map APP records dB level, GPS location, date and time. You can add filters
like event type (landing, takeoff, engine testing) and any notes.
Record options are:
• auto record for 10 seconds - creating an audio file, calculating the average dB level for those 10
seconds, sending the audio file to the database; and
• 3 second recording – by holding your finger on this button, the APP calculates the average dB
level for those 3 seconds
(See previous posts for details on how to get the app)

ARENA’s community noise map APP is about creating a visual representation of what residents are
experiencing, because your experience matters. Please note, this community noise map isn’t to
replace NOISE COMPLAINTS to Nelson Airport. It’s the Noise Complaints that NAL responds to.
Please click here to submit your noise complaint.

Here's the form for those noise complaints. You can include reference to NAL acquiring independent software (as in our previous post).
Purchase and implementation of INDEPENDENT software at Nelson Airport should be a priority!

23/07/2026

What’s available to Nelson Airport Limited, that’s independent, can monitor and report on aircraft noise … something that will aid NAL to be compliant with environmental regulations and manage impacts on the surrounding community??

There is software called ENVIROSUITE and it is currently being used by Wellington International Airport and Port Nelson.

However Nelson Airport Ltd (NAL) advise that it doesn’t meet their requirements and is very expensive.

ARENA will continue to research and provide NAL with suggestions to investigate as we believe independent, transparent and accurate software - no consultants, no reports to summarise - just the plain facts, and should be the priority to fairly and honestly identify houses eligible for mitigation options.

Software that measures:
- noise levels in relation to air noise boundaries
- noises impacting the surrounding community
- runway activity and related noise to ensure operations comply with local council regulations and the airport’s noise management plan.

It is ARENA’s position, that independent software be the first item for NAL to purchase; and given the millions they intend to spend to change the runway (and golf course), this software purchase is a drop in that $$$$ bucket.

Operational Noise Ldn

ARENA has identified, the new measurement process needs to audit measurements against actual readings ie: the data is supplied by Airways Corporation of NZ, but how accurate is this data? Does the data, for example:
a) record flight training circles as just one flight, or the many circuits (touch’n’go) completed within that ‘flight’?
b) include all taxiing to take-off, aircraft wind-up through to take-off noise - is the ‘activity’ of the flight prior to take-off also included in the measurements?

Here's the complaint form if you have reason to complain, particularly about airport noise.

Monitoring of Night Flights

NAL has amended the AIP (Aeronautical Information Publication) effective as of 19 February 2026.

NAL has spoken with operators causing night flight complaints to educate them re: noise mitigating measures at night.

If you think night flights (not medical) are intrusive - put in a complaint!
