Chile Volcano Plume and NZ Airspace
TV3 is reporting that the ash plume from the Chilean volcano may affect NZ Airspace.
No real details other than that ''The Civil Aviation Authority says ash from the volcano, which began erupting on June 4, is expected to arrive in New Zealand airspace as early as Saturday evening.''
Anyone got anything further on this?

It will affect flights if the lower level drops to FL100 as some flights across the South Island will have to be rerouted or canned.
Current forecast for 1200Z is as follows between FL200 - FL350

Was due to fly on QF46 tomorrow CHC-SYD but got an SMS 30 mins ago saying the flight has been cancelled due volcanic ash. QF calling me back in next hour or so to advise the next step
ash cloud
Nothing from CASA, how can that be?

Ash Cloud from Chilean volcano entering New Zealand Airspace
Volcanic ash from the CordónCaulle volcano in southern Chile is expected to enter New Zealand airspace over the weekend.
The CordónCaulle eruption began on 4 June 2011 with the initial ash plume reaching above 50,000ft. Volcanic ash particles come in a range of sizes and while the biggest will fall to the ground quickly, very small particles take a long time to settle out of the atmosphere. This eruption ejected these small particles very high into the atmosphere, where strong winds have carried them great distances to the east.
There is potential for ongoing ash plumes to arrive over southern parts of New Zealand as early as Saturday evening, spreading northwards through the remainder of the weekend. The plumes are expected to be at cruising levels for both jet and turboprop aircraft (20,000 – 35,000 ft), but at the moment not below 20,000ft. Given that the volcanic activity is continuing, it is expected that New Zealand airspace may be affected by these plumes for at least a week.
New Zealand has a mature Volcanic Ash Advisory System (http://www.caa.govt.nz/Meteorology/Volcanic_Ash_Advisory_System.htm) with inputs from MetService, the Institute of Geological and Nuclear Sciences, the Airways Corporation, and aircraft operators that ensures that civil aviation aircraft operations can be safely carried out near volcanic ash. The CAA is also communicating with the Australian Civil Aviation Safety Authority (CASA), to ensure both countries have the latest information available.
MetService, on behalf of the Civil Aviation Authority, operates the Wellington Volcanic Ash Advisory Centre (VAAC) as part of the International Civil Aviation Organisation’s International Airways Volcano Watch system. MetService will track the volcanic ash plumes and provide warnings to the aviation community here and over the wider VAAC area (roughly Equator to the Pole and mid-Tasman to just west of South America).
At this stage the forecast trajectory of the volcanic ash plumes may initially have an effect on air traffic routes over the South Island, the Christchurch to Australia routes, and the great circle routes between Australia and New Zealand and South America. The situation is being closely monitored and other air traffic routes may be affected as volcanic ash forecasts are updated. Based upon information provided by MetService, airlines will adjust their flight routes and altitudes to remain clear of the ash clouds. Safety of the air operations is the primary goal, and flight disruptions will be minimised as much as possible consistent with this objective.

Well Jetstar is now also canceling all services into and out of CHC and Queenstown. Air New Zealand is planning on flying a full program including flights across the tasman from CHC. So it would seem someone is either over reacting or others are under reacting.

craka,
Thats exactly what I was getting at, I can understand that a trans tasman flight might not be viable due to the massive rerouting required. What I can't understand is why Jetstar wouldn't just fly all the domestic services below FL200.
The only reason that I can see is that this has come from Qantas who has instructed Jetstar to not fly due to the risk.

in short no.... There is a portion near Mt Cook that is, but would be very easy to operate in NZL airspace below FL200 and be controlled especially between CHC and AKL - may be a bit congested, but that is better than all those cancellations.
It is almost as if Jet* are finding an excuse to cancel flights citing safety reasons - what are those safety reasons if they can "safely" operate below FL200 IAW the SIGMET - doesn't really stack up. Is it cheaper to cancel due to act of god than it is to operate at a lower altitude.

All QF Tasmania flights including QFLink are canned for today and tomorrow.
It would appear JQ have done the same.
DJ has been stating in news bulletins that they will keep operating but at lower altitude.
I must go now. Need to lower the TV antenna and bring in the washing.
Should be an interesting sunset tonight. The plume is due overhead DPO at 1600 local.
Best all

This is not an excuse for Jetstar to cancel flights!!! 
We have had staff communications today since the cancellations that state it is Qantas policy that flights can't operate 'under' forecast ash cloud which has led to the cancellations for both Qantas and Jetstar. It is an interesting situation as obviously the most safe option is to have aircraft on the ground and not risk a ash cloud encounter. Having said that though, I also wouldn't say that operating at lower altitudes is necessarily unsafe. I guess it comes down to a 'gut call'. What is positive is that at the moment the regulators are leaving it up to the airlines themselves to decide unlike in Europe where there was just a blanket ban.
Does this mean that Qantas and Jetstar have put 'safety ahead of profit, whereas Air NZ and Virgin have put profit ahead of safety. I know Ryanair copped alot of flak in the UK when they said they would be willing to fly under the ash cloud with lot's of people stating that they obviously were more interested in profit!!
