Waitangi National Trust chief executive Greg McManus said the Treaty Grounds were an ideal place thanks to recent efforts to keep the area pest-free.
Nationally, the little blue penguin (korora) population had declined by 60-70 per cent since the 1960s due to habitat loss, vehicles and predation by stoats, dogs and cats, Mr Trimble said.
It was hoped the penguin-box initiative would boost numbers and offer a chance for future eco-tourism and education opportunities such as viewing platforms allowing visitors to see the birds waddle to their dens at dusk.
Bay Bush Action was encouraging people with coastal properties to build their own penguin boxes, monitor their dogs and cats, and carry out pest control to help keep the species alive.
The Paihia pupils' efforts follow a similar project by Opua schoolchildren to install penguin boxes under the Opua Cruising Club. To get the penguin box plans, go to www.doc.govt.nz and search for 'You can help little penguins'.
