Judge Singh granted the brief suppression order and set a sentencing date in February.
Ms Knight, 43, underwent surgery to relieve bleeding on her brain after she tried to stop Hauwai stealing a handbag from Xiao Dong outside Countdown in Northcote.
She tweeted this morning, saying: "Feeling overwhelmed and stressed today. #23SeptReminders".
The mother of six fell and fractured her skull in the incident, which happened in front of her young children.
A Givealittle page set up by friends raised nearly $270,000 for Ms Knight's family.
She previously turned down attending a restorative justice conference with Hauwai.
Ms Knight has also been announced as one of the 10 Herald New Zealander of the Year nominees, the winner of which will be announced tomorrow.
