Mr Judd said today's search efforts hadn't gone well.
"There's nothing to report today, we're scaling things back as well so yeah, not a good day."
Search teams today had scoured the lower reaches of the Wanganui river and along the beach, he said.
"We know the areas that we need to look at, so we no longer require an incident management team.
"Operation-wise [there's going to be] a lot less people involved. We're just going to go back to some of these same areas over the next few days.
"As the river levels continue to drop and the conditions change a bit we'll just keep looking," Mr Judd said.
A tarpaulin and a distinctive hat belonging to Mr Stephens had been found so far, but there had been no other signs of the missing hunter, he said.
"Those were essentially pulled out of the river. Those are leading us to the conclusion that something's gone tragically wrong."
A aerial search involving a helicopter would also take place again tomorrow, Mr Judd said.
