Fatal Favona shooting a case of mistaken identity - report

More than $4000 has been raised so far for the family of a south Auckland woman who was shot dead at her home in an apparent case of mistaken identity.

Meliame Fisi'ihoi was killed on January 16, shot when she answered the door to someone knocking at 2:50am looking for her son, NZME reports.

"She got up and... just said that [her son] wasn't there," a source told NZME.

"They insisted and so she went to open the door and - bang."

There was a shooting at the same Favona property in December, which put a man - believed to be her son - in hospital. 

NZME's source said he might have been targeted because he switched gangs, and his mother - a churchgoing woman who played a big part in the local Tongan community - was "innocent". 

"He's taking it a bit hard now because it's cost his mother her life."

Police said they are still investigating, and have an "open mind" about the shooter's motive. No one has been arrested for either incident at the property.

Fisi'ihoi's son's wife Hannah set up a Givealittle page, which by Thursday morning had $4008 in donations from 56 people. 

"So sorry for this tragic loss to your family. Be strong and hope you receive many blessings," one person wrote. 

"Don't know you guys nor this lovely lady but I am praying for your family," wrote another.

"May God Bless you all and hope you find healing through this."
