Six months after Shane Edwards' mysterious disappearance from a Tokoroa home, his brother remains confident he will be found.

Edwards has been missing since May 14 this year, a passage of time his brother, Australia-based psychologist Dr Michael Edwards, says has included a number of whānau milestones.

In a sombre list of occasions his brother has been 'absent and unaccounted for”, he listed their mother's birthday, sister's birthday, Father's Day, his eldest son's birthday and youngest son's birthday.

His partner Alvina Smith told Stuff back in June that he'd made lunch for everyone and later offered to clean up while Smith and their children were in their bedroom.

'He's meant to be doing the dishes. I came out in about 20, 30 minutes. Dishes are there but he's not there.”

That was the last time Smith, and their children, saw Edwards,

She immediately knew something was wrong, she says.

'It didn't take a while ... It was in that moment.”

She says for him to vanish like this was completely out of character.

'He's a good dad. No gangs, no drugs, no mental health issues. Not for Shane. He loved being with the boys, they meant the world to him.”

Smith also told Stuff what her message would be to Edwards.

'Come home hun. The boys miss you, we all miss you.”

According to Detective Sergeant David Whitecliffe-Davies, the man in charge of the search for Edwards, his disappearance is still 'completely out of character”.

He says the last possible sighting was two months ago in Paihia, 'of a similar looking man trying to get to Tokoroa”.

'We were later able to confirm this was not Mr Edwards,” he says.

'Prior to this, there have also been reported sightings in Rotorua and Whakatāne, again we were able to confirm these were not Mr Edwards, this time through CCTV footage.”

Whitecliffe-Davies also gave an insight into how the police search for Edwards has been conducted.

'When there is CCTV footage available or a line of inquiry we have followed them until we have been able to rule it out,” he says.

'There are some we haven't been able to rule out entirely because we have no way to confirm the identity of the person sighted.

'In those cases, we have used a range of methods, including flooding those areas with flyers. At this time, there are no leads from reported sightings that we are following up on.”

He also says they remain 'committed to try and give the family some answers”.
