Korewha said Ms Moka wanted to go for a drive about 1am on June 9 while his whanau were having drinks after his sister's tangi at the marae.
As they got round a corner, he said Ms Moka became upset and remarked "Back to life, back to reality", before she swung the car into a ditch because he wasn't listening to her.
After he didn't reply to her remark, Korewha said she asked him: "Do I have to put you in front of the marae or the taumata for you to reply?" Korewha told police he didn't know where the conversation was going.
Korewha's cousin, Charlie Reid, who was on his way home, gave the couple a lift to the marae after their car crashed.
After getting back to the marae, Korewha said he went to the toilet and Ms Moka prepared to roll a cigarette.
When he returned to the smoking area, Korewha said she was not there or in the marae.
He texted his sister and other family members that day to check if they had heard from Ms Moka.
About 9pm that day, Korewha said he decided to return home to Rawene for a shower and discovered Ms Moka's cellphone on the charger, clothes on a couch and heard someone in the shower.
Korewha said he freaked out at finding her at home because the only keys were with him.
He thought she had crawled through a window to gain entry.
Korewha said he didn't ask her how she got inside but was just glad she was back.
He said Ms Moka got dressed up and said she was going out.
He said he followed her and she yelled at him from across the road that she wanted to be left alone.
That was the last time he saw her.
Korewha said Ms Moka found it difficult to work 35 to 40 hours a week and wanted to get her children back.
The trial continues next week.
