Police cordoned off the house and requested the armed offenders squad be dispatched from Wellington as a precaution.
"They had the place cordoned and believed that he was in there but after they got the other occupants out, they were informed that he had run off before the cordon was in place."
As the risk had gone down, the armed offenders squad was stood down before reaching Featherston, he said.
A dog handler had been deployed in the area around the house, but had failed to find Dickson.
Dickson is wanted on a Corrections matter and is described as European, 184cm tall and of medium build, with distinctive tattoos on the right side of his neck and on the back of both hands.
Police said he should not be approached.
He has links to Lower Hutt, Kapiti and Wairarapa, and police believe he is likely to be in the greater Wellington area.
Police also want to speak to Dickson on an unrelated matter that happened in Masterton on January 13.
Anyone with information regarding Dickson should call Masterton police on (06) 370 0378, or alternatively call anonymously via Crimestoppers on 0800 555 111. Sightings of Dickson should be reported on 111.
