A helicopter, seen flying low over the Hatea River, is being used as part of the search for Smith.
A police spokesperson said at this stage there were no plans to continue the search upon nightfall unless they receive information or leads that need immediate action.
“Police, alongside Search and Rescue (SAR), will assess the plan going forward as and when and will make decisions depending on variables, such as weather conditions.”
Police anticipate the search will resume tomorrow.
They and Smith’s family had serious concerns for his safety.
Smith is described as tall, with short brown hair and of slim build. He was last seen wearing a pair of black Hunting and Fishing trackpants, and a long-sleeve polar fleece shirt with dark green and black squares on it.
“We continue to ask anyone who has any information or knows the whereabouts of Veon, to please contact police.”
Anyone who has found anything unusual in Mair Park or on Parahaki is asked to call 105 and quote file number 230604/1348.
