“Rein Me In” peaked at number 2 on the New Zealand singles chart.
The song by Sam Fender and Olivia Dean reached the runner-up position on New Zealand’s Official Top 40 Singles chart. It did not reach number one there, despite topping the charts in the United Kingdom, Australia and Ireland. The New Zealand result therefore stands as a peak of 2, not a chart-topping performance.
“Rein Me In” was originally a solo Sam Fender song from his 2025 album People Watching. The charted duet version added Olivia Dean’s vocals and was released as a single in June 2025. Its later international success followed a gradual rise in the UK, where it eventually reached number one after a 35-week climb.
A useful distinction is between a song’s peak position and its wider commercial performance. A number 2 peak can still accompany strong sales, streaming and certifications; in New Zealand, “Rein Me In” was certified triple platinum even though it stopped one place short of number one.
