Decision for Emergency Mobile Alert to remain a non-
opt-out channel 
2 July 2018 
Purpose 
This paper summarises the considerations and decision by the Cell Broadcast Alerting Steering 
Committee to continue broadcasting Emergency Mobile Alerts solely on a non-opt-out channel. 
Background 
The detailed business case for a national public alerting system was considered and endorsed by 
Cabinet in July 2016.  
The  business  case  identified  that  Cell  Broadcasting  technology  is  the  delivery  system  that  best 
meets the requirements given it is purpose built for public alerting and is not affected by network 
congestion.   The system would ensure people are being warned directly about imminent threats 
without first having to subscribe (opt-in) to the system. The business case described the need for a 
non-opt-out  cell  broadcast  channel  and  the  implementation  of  an  opt-out  channel  was  not 
requested.   
It was acknowledged that while there are obvious benefits for the public of being warned directly 
about imminent threats, some people may, in principle, oppose receiving alerts that they have not 
explicitly requested or agreed to receive, and that they cannot turn off. Therefore, it was noted that 
the system will have: 
a.
effective governance and protocols for agencies who use the alerting system;
b.
thresholds  for  alerting  people  of  critical  emergency  situations  that  are  reasonable,
proportionate, and justified;
c.
alerts targeted to specific locations so they are relevant only to those people at risk;
d.
technology that allows people to choose not to receive alerts that are non-critical;
e.
no commercial advertising or marketing (spamming); and
under the Official Information Act 1982
f.
an effective public education, promotion and engagement strategy.
Point ‘d.’ above does not apply, as the system is only used for critical alerts, i.e. when there is a 
severe threat to life, health or property. Therefore, only one non-opt out cell broadcast channel has 
been established. 
Public feedback following the nationwide test in November 2017 and the New Plymouth boil water 
alert  in  February  2018  indicated  some  phones  repeatedly  received  alerts.  The  issue  was  most 
obvious  during  the  four-day  long  New  Plymouth  boil  water  broadcast.  The  repeated  alerts 
Released 
inconvenienced some recipients and caused frustration. 
The  New  Zealand  mobile  operators (2Degrees, Spark  and  Vodafone)  were  engaged to  conduct 
further testing on the behaviour of phones when an Emergency Mobile Alert is received.  The testing 
was  completed  in March  2018  and  revealed  that  some  phones that  have  not  been  upgraded  to 
make them compatible with New Zealand  Emergency Mobile Alerts  have an underlying cellular 
broadcast  capability  that  can  cause  the  phone  to  receive  repeated  alerts.    Unfortunately  these 
phones  cannot  be  fixed  with  a  software  update  as  the  phones  are  not  able  to  receive  software 
updates from the New Zealand mobile operators. We anticipate this issue will become less frequent 
over time as people naturally replace their phones.
Ministry of Civil Defence & Emergency Management

To  reduce  the  effects  of  Emergency  Mobile  Alert  on  these  phones,  the  mobile  operators 
recommended: 
•  Avoid broadcasting messages over prolonged periods; 
•  Using  an  opt-out  channel  so  that  people  can  choose  to  opt-out  if  their  phone  is 
receiving repeat alerts. 
 
Considerations 
On  22  May  2018  the  Cell  Broadcast  Alerting  Steering  Committee  discussed  the 
recommendation from the mobile operators to use an opt-out channel.  Key discussion points 
1982
were:  
•  Some phones have an underlying cellular broadcast capability that causes the phone 
Act 
to  behave  in  a  way  people  find  irritating  and/or  distracting.    Repeat  alerts  are  an 
example of this. 
•  A small percentage of the public previously complained about the inability to opt-out 
of  Emergency  Mobile  Alert  messages  when  we  issued  the  nationwide  test  in 
November 2017.  Some people strongly believe it is their right to be able to choose 
whether they receive alerts.  
•  The nationwide survey conducted immediately after the nationwide test in November 
2017 asked the public whether we should have an opt-out channel. 72% of mobile 
Information 
users believe New Zealanders should not be able to opt out of the EMA system. 21% 
think it should be optional and 7% don’t know.   
 
•  The primary reason for the investment in the Emergency Mobile Alert system was to 
help  keep  people  safe.   Alerts  are  only  sent  when  there  is  a  serious  threat  to  life, 
health, or property. 
Official 
 
•  An annual test is necessary to prove the system will work in emergency situations, 
both  for  the  user  agencies  and  the  public.  It  also  ensures  that  the  public  has 
the 
experience of the appearance and sound of the alerts. 
 
•  If someone who was injured or killed was not alerted, and it was determined that the 
reason  is  because  an  opt-out  channel  was  used,  then  questions  would  rightly  be 
asked  about  why  the  Steering  Committee  chose  to  make  an  opt-out  channel 
under 
available.    It  is  unlikely  to  be  viewed  positively  if  the  rationale  to  use  an  opt-out 
channel was because committee members did not want to irritate people. 
 
Decision 
Committee  members  concluded  that  it  is  appropriate  to  continue  to  broadcast  Emergency 
Mobile Alerts on the non-opt-out channel given the life-saving nature of the alerts.    
Released 
The Committee acknowledged that this may cause inconvenience and annoyance to some 
people. 
The  Ministry  of  Civil  Defence  &  Emergency  Management  will  work  with  the  agencies  that 
issue Emergency Mobile Alerts to ensure they understand and where possible mitigate the 
concerns raised by the public.  For example, only running long duration campaigns during 
daylight hours.

fyi regarding EMAs, from s9(2)(g)(ii) NEMA Staff if we're seriously considering EMA for this
that we need think about how a nationwide one might work vs multiple groups.
If multiple groups send, then those who are on the boundary between groups
will get multiple messages. We also need to make sure that the groups are all
saying similar things so people don't receive conflicting messages.

The threat is likely to remain in force until at least midday today.
Act 
Tsunami activity has already reached parts of New Zealand. The first currents

boats unless instructed by officials.
IF YOU ARE ONSHORE, YOU DO NOT NEED TO EVACUATE. But STAY AWAY

Key messages
• This current threat level expected to last at least until 3pm 31 July

• Some parts of NZ could be under Beach and Marine threat for roughly 2
days
• This information will be reviewed on an ongoing basis based on arrivals at
NZ DART and tsunami gauges – next TEP meeting 2pm
• Estimated travel time to Scott Base is NZ + 7h (arrival time, i.e. 7am NZT
31 July) and at the same level of threat as NZ i.e. Beach and Marine and
estimated duration should be roughly similar
• The threat map remains the same

 Update from the TEP - they are continuing with the same threat level for the
whole country at this time. They next meet at 1400 and have criteria for being
able to de-escalate the threat across the west coasts of both islands. It is
anticipated this will come into place mid afternoon.
 
Due to the reflections off South America, there continues to be a possibility for
continued beach and marine threat overnight for the east coasts. Chatham

Call recieved from the NGMC: There has been a de-escalation to most of the
West Coast, however they advise "Going below Beach and Marine does not

mean the absence of tsunami impacts, potentially strong and unusual currents
can still occur on the West Coast.". 
Act 
• TEP is still waiting on reflected waves from the Americas to inform
decisions for the East Coast.
• This current threat level expected to last at least until 7:30am on 1st August
• Some de-escalation is likely between 7:30 a.m. and midday on 1st August.
Parts of New Zealand could remain under Beach and Marine threat for

Please note, due to rebounding tsunami activity from South America, the east
coast of both the North and South Islands and the Chatham Islands remain

under a National Advisory, and are likely to remain so overnight.
The remainder of the West Coast of the South Island and Cook Strait that
remain under a Beach and Marine Tsunami threat are assessed as only just
reaching the threshold for a Beach and Marine Tsunami threat. 
 
A further update will be provided at approximately 0800 NZST tomorrow.
