Is Slingshot legit?

Legit, mixed reviews

You are dealing with a real internet provider at Slingshot, now part of 2degrees, but leaving a contract early is where bills tend to bite. Inside the minimum term its terms add an early termination fee, and after a price rise that fee is only waived if you give notice before the new price starts.

What we checked

  • Internet provider since 2001
  • Trading name of CallPlus Services
  • Registered office in Auckland
  • Ratings on other review websites: 1/5

Watch out for

  • Switching to another provider mid-contract, when the move still carries Slingshot's early termination charges.
  • A payment made on time that does not show on the account, followed by an overdue notice.
  • Broadband that keeps dropping out, with fault references spread across several calls and emails.

Charged to leave your Slingshot contract early?

We help you write it, it gets its own public page, and you can have it sent to Slingshot as a formal letter.

Outage, bill or cancellation fee to dispute? Start your complaint here and we push it out to Slingshot by email, social media and printed letters.

How do I cancel Slingshot broadband?

To cancel Slingshot broadband, contact Slingshot by phone or email with your account number and the date you want the service to end, and ask for written confirmation. Check your plan first: a fixed-term plan can carry an early termination fee, and a bundle may change price when one service leaves. When you switch, the new provider often arranges the change, but confirm with Slingshot that the old account is closed and ask for the final bill.

Early termination fee you dispute? Our trained AI opens a case for you and keeps coaching: what to reply, when to push and how to escalate.

What can I do when Slingshot internet is not working?

When Slingshot internet is not working, check the outage checker Slingshot links to from its contact page, then restart the modem and test with a cable if you can. If there is no known outage, report the fault to Slingshot and note the fault reference, with the dates and times the connection dropped and any speed test screenshots. Repeated outages are worth raising as a complaint, not only as fault reports.

Can I take a Slingshot complaint to Telecommunications Dispute Resolution?

Yes: Telecommunications Dispute Resolution handles complaints about phone and internet providers in New Zealand that belong to its scheme, and Slingshot is a member for its broadband and home phone services. It generally expects Slingshot to have had the chance to put things right first, so keep a record of every contact with the company.

Set it out through our complaint process: we help you write the complaint in minutes, with every outage and fault reference in date order.
