A quick update to let you know you are not alone in the outages and frustrations!

Many cell towers from all telephone communication companies have been severely impacted by Cyclone Gabrielle. They are working to restore cell coverage and internet as fast as they can. Many people have no coverage or intermittent. Best to contact your provider to see what they can do for you. Also follow their FB pages to see updates etc.

Here are some tips from RNZ that may be helpful now or in the future:

Fixed line internet

If you are on an ADSL or VDSL connection (via your phone line) and the power in your area or a neighbouring street is out: These often run out of street-side cabinets that use the same mains power as the properties in the street.

When power to the cabinet goes off, a battery-based uninterruptible power supply in the cabinet will take over - for something like 24 to 48 hours. Once this is exhausted, your DSL connection will go down as well. Use it before it dies.

Mobile data / text / calls

Mobile data is an alternative to fixed line Internet but not available with sufficient capacity everywhere. In an emergency, stick to text and voice calls as much as possible, also text-based messenger apps, to conserve battery power both for your phone and for the cell sites. Minimise use of video calling. It's also not a good time to hunker down with Netflix, TikTok, YouTube, Vimeo, or any other video-based application.

When using your mobile, try to go to a place where you get a good signal: Outside, ideally within direct view of the cell site, as close to the cell site as possible (if you know where it is and of course if it is safe to do so). The fewer walls, windows and obstacles, the better. Coarse rule of thumb: halving the distance to the cell site means using one quarter of the power, so your battery lasts a lot longer. Keep communications short.

Turn mobile phones off that aren't needed: If the entire whānau are together, work out who really needs to operate their phone and who doesn't. Phones "talk" to cell sites even if they are not actively calling / texting / surfing and this also drains batteries at both ends.

Consider using SIM cards from two providers in a dual-SIM phone: If one network can't provide coverage, another might.

Wireless / Satellite internet

There are a number of providers in New Zealand offering such services, e.g.: Gravity (getgravity.nz, satellite), Woi (woi.co.nz, satellite), Uber NZ (uber.nz, terrestrial wireless, nothing to do with the taxi company), Wireless Nation (wirelessnation.co.nz, terrestrial wireless), Farmside (farmside.co.nz, terrestrial wireless) and others.

If your usual provider is not able to help where you are, they may be able to. Expect them to be crazy busy right now, though.

Starlink

This is a satellite service available across NZ (starlink.com) based on an up-front hardware cost and a monthly subscription. It is relatively easy to set up compared to other satellite services and mostly plug and play, giving you a WiFi router as part of the package. You need a spot with a relatively clear view of the southern sky or it will not work all that well.

There are also limits to the number of users Starlink can support in a given area and in some areas in New Zealand, this limit has been reached and Starlink will defer orders from those areas until more capacity is available (starlink.com has an availability map).

Comparable in performance to a good ADSL/VDSL connection and sometimes better than that, depending on where you are and how many other users there are in your area. It will take a generator or mains power to run - it consumes about 100W at peak.
