Newman told the Rotorua Daily Post just after the mugging that she was so terrified she didn't want to leave home.
She said yesterday that she had since returned to work and her injuries had healed.
"I'm doing much better and have to get out because of the children but I try not to go out at night.
"I just hope they can get him soon."
Her husband, Fraser Newman, posted a message on Facebook hours after the attack, appealing for witnesses.
He said he was glad he did it because it had helped him and his wife with support as well as the police investigation.
He said once the robber had been found they intended to take a civil case against him as well as support police with a criminal case.
"We [the Newmans and the police] are looking for him and it is only a matter of time so it's best he hands himself in."
Police have confirmed no one has yet been arrested.
