Spark Mobile Call Forwarding (Conditional Diversion) – New Zealand

[Andy]

For Spark Mobile in New Zealand (Spark SIM / Spark phone plan), conditional call forwarding (also called call diversion) uses standard GSM / USSD codes. These work on most Android and iPhone devices.

Set Conditional Call Forwarding (Spark NZ)​

Replace +64XXXXXXXXX with the destination number (use +64, drop the leading 0).

• Forward when unanswered/no reply: *61*+64XXXXXXXXX#
• Forward when unreachable/offline: *62*+64XXXXXXXXX#
• Forward when busy: *67*+64XXXXXXXXX#

Tips​

• On some networks/devices, you can adjust rings/delay, e.g., *61*+64XXXXXXXXX**11# for 11 seconds, but Spark typically uses fixed/default timing.)
• If a code fails (e.g., "connection problem" or no confirmation tone/message), try adding *11# at the end: *61*+64XXXXXXXXX*11#.
• Each condition works independently.

Disable Call Waiting (Recommended for “Busy” Forwarding)​

If call waiting is enabled, your phone won’t show as busy.

• Dial #43# to disable call waiting
• Re-enable later with *43#

Check Status or Disable​

• Check unanswered: *#61#
• Check unreachable: *#62#
• Check busy: *#67#
• Disable one condition: #61#, #62#, or #67#
• Cancel all forwarding: ##002#

Notes​

• Forwarded calls are charged at normal plan rates
• Default Spark voicemail: 08320 0000 or +64 8320 0000
• Conditional forwarding replaces voicemail
• Test after setup
