A Mediaworks spokesperson told the Herald: "A third of the way through the season and The Block NZ continues to grow from week-to-week and continues to beat its competition. It appears the tribe has spoken."
Today, a TVNZ spokesperson told the Herald: "A decision has not yet been made on a season three of Survivor New Zealand."
The disappointing ratings continue a troubled run for TVNZ, following mediocre ratings for its reality dating show, Heartbreak Island.
An average audience of 80,000 viewers aged 18-49 tuned in across Heartbreak Island's first season, lower than TVNZ might have hoped for.
A second season of Heartbreak Island has been confirmed. TVNZ says it plans to adjust the format before its return, based on viewer feedback.
"Listening to audience feedback enables us to bring the very best programme to air. We did this for Survivor season two and Heartbreak Island will be no different. We'll incorporate some viewer tweaks to further strengthen the format for season two."
