Spark simulcasts All Blacks on free TV after issues

Spark Sport have been forced to simulcast the All Blacks Rugby World Cup opener against South Africa on TVNZ's free to air channel Duke.

"Due to a small percentage of our customers experiencing streaming quality issues when watching Spark Sport on certain devices, a decision has been taken to switch live play over to TVNZ Duke," a Spark Sport statement said.

"The New Zealand v South Africa match is now playing live on both TVNZ DUKE and Spark Sport."

"For those customers who are experiencing a poor stream via Spark Sport, turn your TV to channel 13 or DUKE on Sky channel 23. This match is not available through the TVNZ website or TVNZ OnDemand app," the statement continued.
