Police have confirmed a person recorded as being allegedly murdered by the Christchurch terror attack shooter is not dead.

After RNZ reporters reviewed names and numbers of the dead, it was discovered that there were 51 names, not 50.

After getting confirmation from police one person was wrongly named as dead, the total number remains at 50.

Police wrongly charged the Christchurch shooter with the murder of a person who - it has emerged - turned out to be alive. That person's name is suppressed.

A police spokesperson said an error was made in the document laid in court during the first appearance of Brenton Tarrant.

Police said they apologised to the person incorrectly named on the document and would amend the document.

Police Minister Stuart Nash appeared on RNZ's Checkpoint tonight and said he had only been told about the error 10 minutes before he was on air.

"It was an administrative error and it will have no bearing on the process.

"Let's bring this guy to justice."

When asked how they had found out about the error, he said: "You're probably best to talk to [police] Commissioner Bush on that.

"It will make absolutely no difference."
