Police are checking CCTV footage after reported sightings of missing Tokoroa man Shane Edwards in Auckland, Maketū, Waikaremoana and Tīrau.

The officer in charge of the case, Detective Sergeant Dave Whitecliffe-Davies, also told Stuff they have ruled out earlier reported sightings of Edwards in both Whakatāne and Rotorua.

Dave says a lot of the reported sightings have been one-off claims, and hard to verify.

'We just haven't been able to say whether they are [Shane] or not.”

He also warns that, in the month since Shane was last seen, it's possible his appearance may have changed, with different facial hair, or longer or shorter head hair.

His message to anyone who believes they may have seen Shane, or thinks they may know something about his whereabouts is unchanged – get in touch with police.

'Even if it's only a small percentage chance,” he says.

Shane's disappearance on May 14 has left his whānau, and police, baffled.

'It is very unusual and that's making us worry a bit,” Dave said last week.

'Absolutely nothing leading us towards what could have happened. Usually you get some sort of angle. Usually there's some information, even if it's only false leads.”

Stuff also spoke to Edwards' partner of 18-years, Alvina Smith, who reveals how Shane simply vanished from their Tokoroa home, and about the devastating toll his disappearance has had on both her and their four children.

On the day Shane disappeared, Alvina was in their children's bedroom and he'd said he would clean up the lunch dishes, she says.

When she went into the kitchen 20 to 30 minutes later, he had simply vanished.

She says for him to vanish like this is 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,” she says.

'He takes them to school, wakes them up, makes lunches, changes them, helps me do their breakfast. If one of them is upset after school he might treat them at the dairy or take them to the rock path. That's something fun for them, or the park.”

She says their four boys are suffering too.

'They don't want to go to school. They're asking for him all the time.”

'Our baby always asks, maybe he's down this way, maybe that way, maybe we should look here. I've got another son saying ‘Oh he'll be home soon mum, I miss him too', I have to hear the same stories every night.”

The toll on Alvina is obvious too.

'I don't eat, just constantly worried,” she says.

'I was keeping count [of the time], but after a month ... it's every minute, every hour just drags.”

Asked what her message would be to Shane, it takes Alvina a few moments to get the words out.

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