"An error was made in the charging document prepared for the first court appearance of the man charged with murder in relation to the Christchurch terror attacks.
"The error saw an incorrect victim name included in the charging document.
"We have spoken with the person incorrectly named on the charging document and apologised.
"The charge sheet will be amended. New Zealand Police regret this error and apologies for any harm caused by the mistake."
Police told media charge sheet details would be amended at the accused's next appearance on April 5.
The error would not affect the validity of the prosecution.
Fifty people died when a gunman opened fire with semi-automatic firearms at two Christchurch mosques last week.
The accused man was arrested just 21 minutes after the first 111 call was received.
The man has indicated he will represent himself during further court proceedings. It is understood he is being held in segregation at Auckland's maximum security prison.
