People wishing to attend a Muslim memorial should refrain from wailing and shrieking, according to the New Zealand Muslim Association.
Local Muslim community leaders are planning to hold a national memorial burial for the 50 victims of the Christchurch mosque shootings later this week.
While it is acceptable in Islam to express grief over death by crying and weeping, the association said on its website, "wailing and shrieking, tearing of clothing and breaking of objects, and expressing a lack of faith in Allah are all prohibited".
Graves are now being dug in the dedicated Muslim section at the Christchurch City Council-run Memorial Park Cemetery in the eastern suburb of Linwood.
Funeral prayers, or Salat al-Janazah would be recited by members of the community at a mosque, with those praying facing the "qiblah" or Mecca, before the body is transported to the cemetery for burial.
