Issues occurred for customers more than 15 minutes before kickoff, including streaming disruptions during the haka.
Customers took to the Spark Sport Facebook page to express their frustrations.
"Not only will the games not stream your screwing the net up for other programs too!!!," one customer said.
"We're having the SAME problems! What are you doing to fix this? Getting pretty sick of getting up n down every 2 minutes," another added.
The comments continued.
"It's been buffering like this for the last 20 minutes... Spark Sport ruining the rugby world cup again... Get it together..," said another
"Just missed the All Blacks haka again," one customer said.
"Are you serious spark sport? Game hasn't even started and we are being told please try again later!," one fan added.
Spark Sport told customers on social media "the metrics we monitor show no issues stream-side".
Spark said they had no issues with the All Blacks' last pool game against Canada on Wednesday.
"Last night was very quiet for the Spark care team. We saw lower numbers of people contacting customer care than we had expected, relative to the number of people watching the match," a spokeswoman said.
"Key performance measures tracked well and the vast majority of customers had a great viewing experience. There were no system-wide, device or service-specific issues last night."
