The 10 students from Carterton's South End primary school that were hospitalised due to an unusual smell will be back at school tomorrow.
Police now believe they can rule out initial reports that a plane flying overhead may have dropped a toxic substance on the school.

Multiple students fell ill on Friday afternoon following reports of an unpleasant smell.
Originally the smell was thought to have come from a plane that flew near the school but police have ruled that out after speaking with the pilot.
South End board of trustees chairman Brian Chin said it will be business as usual tomorrow for everyone at the school, including the children who fell ill.
"All children were discharged on Friday evening. They were sent home with information about what to do if they feel unwell again.
"They have contact numbers on hand if they feel unwell again and at this stage we envisage all those children will be at school again on Monday," Mr Chin said.
Wairarapa Area Commander Inspector Scott Miller said the police were turning their focus to neigbouring properties and the surrounding area to find the source of the smell.
"There will be a couple of people in the [neigbouring] houses that we haven't spoken to and we'll be looking closely at the area to see whether there's anything in our police intelligence systems that may indicate where this smell may have come from."
Up to 40 per cent of older New Zealanders are engaging in hazardous drinking, a study has found.
Researchers from Massey University and the University of Auckland explored the prevalence of hazardous drinking in 4000 New Zealanders aged 50 years and over.
Hazardous drinking was defined as alcohol consumption that puts the person at risk of immediate harm, such as hospitalisation, or long-term harm such as cancer.
About half of older males and a quarter of older females were hazardous drinkers.
Research co-leader Dr Andy Towers said he wasn't surprised by the results.
"What we know from around the world is that we have a cohort of baby boomers that are drinking much, much more than any previous generation of retirees before.
"Drink is the drug of choice for baby boomers."
While awareness campaigns mainly focus on binge drinking in young people, little is known about harmful alcohol consumption in older adults.
"Our discussions about alcohol use shouldn't just be about binge drinking or whether someone has a problem... hazardous drinking is about how much you're drinking and whether - even it's a low amount - whether it's appropriate if you have medication use and [if] you have certain health conditions."
There are greater risks for older drinkers as their bodies become more sensitive to alcohol, Dr Towers said.
"We're not down to the point where we can provide really nuanced information or guidelines, we just say, in general, if you have this and you have this and you're taking medication, you really shouldn't drink."
The research team is now working with the Health Promotion Agency with the intention of developing a GP alcohol screening tool.
"One of the big problems we have is that a lot of GPs, a lot of practice nurses, feel uncomfortable talking to older adults about alcohol.
"We need to start talking about alcohol use with our parents and our grandparents."
The study reveals that New Zealand youth drinking culture is actually a "New Zealand culture" issue, Mr Towers said.
