Observers may have noticed parts of Rotorua looking a little sharper with berms trimmed, rubbish cleared, and lawns neatly edged. That tidy-up was driven by local rangatahi (youth) who have stepped forward to give their streets a festive spruce-up. A crew of about a dozen young people, led by Waiariki Whanau Mentoring youth mentor Thomas Peato, has gathered once a week through December for a full day of maintenance mahi (work). He joins Bryan for a chat.

Senior lecturer at AUT, Dr Amandine Sabadel is a chemist, ecologist, environmental scientist and an eel expert. She's with Bryan to discuss why finding where they breed is so important - and why it's proving so difficult.

We think it's a good idea to recognise some of those who'll keep working through the summer break, so that the rest of us can enjoy a holiday. We've chatted to a nurse and a fire fighter - and today, it's a ranger. Riki Bennett is Ngahere Ranger in the Waitakere Ranges - he joins Bryan for a chat.

Food waste, wrapping paper, plastic packaging - Christmas can be a wasteful time. Georgie Ferrari, Chief Executive at Sustainability Trust, join Bryan to discuss the practical steps we can take to have a sustainable holiday.

Part two of our Staycation - or urban vacation series - depending on where you live. Today - Te Whanganui O Tara - Wellington, with Simon Woolf, who's well qualified, first because he lives there, secondly, because he's just written a book about the city, Wellington Moods.

Summer is the season for walking. Doug Haynes is walking Te Araroa, the National Trail. He's a golf caddie by trade and obviously loves his job, because he's carrying two sets of golf clubs with him - either that or he's stopping at every golf course along the way. We're not sure whether Doug is heading north or south, but he joins Bryan on the line from Taumarunui.

Alice Taylor is joining Bryan across the week to give yummy and simple Christmas gift ideas.

Now here's a challenge for anyone with children - find things to do that get them off their screens, get them moving and won't hit parents in the pocket. That's where Bryan's guest comes in. Dr. Susannah Smith is President and Board Chair of Physical Education New Zealand and an Associate Professor at University of Canterbury.

Christmas is a time when many of us head back to the family home - the marae - and in the case of many Pacific Islanders - the village. People like Kayla Tuara are taking their family back to the Cook Islands for Christmas. Kayla joins Bryan from Rarotonga.

We reckon it's a good idea to recognise some of those who'll keep working through the summer break, so that the rest of us can enjoy a holiday. Yesterday it was Ian King - on call most of the summer break for the Otaki Volunteer Fire Brigade. Today on the run home to Christmas, we celebrate the work of Holly Rawiri, Duty Nurse Manager at Taranaki Hospital.
