Telecoms not treated as major priority during Cyclone Gabrielle - new report

Critical equipment for fixing telecommunications was unloaded from aircraft and replaced with other gear, on flights into regions cut off by Cyclone Gabrielle.

鈥淒ecisions were made about other items being [more] essential,鈥 according to聽聽into the stop-start emergency response, which said telecommunications should have been the top priority.

This 鈥渨as not properly understood by the people coordinating the emergency response, nor was it built into the framework for dealing with emergencies鈥.

It gave three other examples of this:

  • 鈥淥ur technicians and the vehicles [including helicopters] carrying them were not considered essential, so had restricted access or were sometimes denied access to affected regions to repair infrastructure.鈥
  • 鈥淪ome regions did not get small mobile cell sites on wheels鈥 because a frigate left earlier than advised.鈥
  • 鈥淭here were no clear formalised processes, eg, to prioritise electricity restoration to key telecommunications sites.鈥

Only two cell sites were actually damaged by the storm, but 1600 others across Northland, Auckland, Hawke鈥檚 Bay and Gisborne went dark due to the power cuts,聽聽from the company-run Telecommunications Forum said.

The two reports were part of a patchwork of reviews into the cyclone response, resilience and what to do now.

At the cyclone epicentre on February 14, with mains power lost, the Napier communications hub was relying on generators to keep two entire networks going.

But fuel began running low, spurring a plea - revealed in OIA documents - from the Telecommunications Forum: 鈥淲e urgently need the fuel plan from NEMA [the National Emergency Management Agency].鈥

鈥淭he lack of prioritisation for telecommunications by NEMA and聽聽caused major issues for telcos trying to coordinate transport of equipment into affected areas, access into areas and access to fuel,鈥 the new report said.

The companies got together and began fixing things in the first five days 鈥渨ithout a lot of coordination via NEMA鈥 - but with lots of 鈥渄istraction鈥 due to requests for updates from the government in 鈥榯he bunker鈥 at the Beehive.

鈥淎t times it was difficult to understand where power restoration was being prioritised.鈥

NEMA said it was 鈥渦ndertaking a review into its own actions鈥 and not 鈥渃urrently in a position to reflect in detail on the response as it is important we first let the review process run its course鈥.

Demand to do better

The Telecommunications Forum report into improving resilience listed several ways the industry and government could do better.

Just how tenuous things were is attested to here: 鈥淣etwork outages resulted in all [fibre optic] north-to-south traffic being reliant on the Western Core fibre route via New Plymouth. This was a considerable risk.鈥

RNZ has reported on other documents that show the lifeline services - telecoms, water, power, roads - have hardly any resilience standards imposed on them by regulation. One of the few rules is that Chorus must spread its 鈥減oints of failure鈥 so that no one failure can take out more than 4000 connections at once.

The 20-year-old Civil Defence law was of 鈥渓imited鈥 use, officials have told ministers. It required lifelines to be 鈥溾榓ble to function to the fullest possible extent, even though this may be at a reduced level, during and after an emergency鈥, but lacked monitoring and other powers.

The replacement law now before Parliament has an aim of 鈥渕odernising the treatment of lifeline utilities, including renaming to critical infrastructure and clearly setting out the roles and responsibilities of critical infrastructure sectors and entities鈥, but is contentious, with聽聽the raft of reforms around infrastructure would return enough benefits.

Who pays for disaster-proofing critical national infrastructure has become a big question following Gabrielle.

Spark has聽

The Telecommunications Forum has a major vested interest in this.

Its new report said companies already 鈥渋nvested heavily鈥 in disaster-preparedness. However, it also had many suggestions about what more to do, including during a disaster:

  • identify key cellphone towers to restore
  • prioritise: 鈥淲e would like to hear government views about services that need priority (eg emergency services, hospitals...)鈥
  • standardise data reporting, sharing of staff and resources, and communications with government agencies
  • improve ways for getting spare parts.

And before a disaster:

  • co-invest with government in back-up power supply for crucial communication hubs
  • co-invest in duplicate fibre links in low-population areas - 鈥淲e have an initial list of regions to discuss.鈥
  • lay secondary fibre-optic and other cables on different roads into major centres
  • using Transpower pylons for cables, not bridges
  • update engineering standards, including for river crossings
  • put fibre under the sea - 鈥淲hile this 鈥榖lue skies鈥 option could have the most impact, it is likely to be very high-cost.鈥

The forum鈥檚 case is based on telecommunications being number one to restore from the start.

鈥淏eing able to get emergency assistance, to understand what was happening or who was affected, and to find out if loved ones were safe was essential for people in affected areas and for those trying to help them,鈥 its report said.

鈥淏y day two or three the priority was still communications: to be able to use electronic payment systems to buy food or fuel, and to coordinate restoration work.鈥

Moves being made already to improve resilience include:

  • more satellite connectivity for cellphones if mobile networks are down - but power cuts took out this backup, too
  • extending roaming beyond 111 calls only
  • storing generators in high-risk locations - 鈥淲e have a lot of generators - there is now a question about where to store them and how to keep them maintained.鈥

The 鈥済old standard鈥欌 for resilience simply was not commercially viable in some areas, the report said.

鈥淚t is not commercially viable to build redundant cellular coverage in areas where it will not be used often.鈥
