    Roadtrip to Raglan (Whāingaroa): Part 1

    Roadtrip to Raglan (Whāingaroa): Part 1

    Join Tim and Waveney on a road trip to legendary surf town Raglan (Whaingaroa) to uncover the stories behind the town’s long history of ground breaking successes in sustainability. 

    In this episode we meet four locals. Two who have been part of rebuilding the standard small town economic model of shipping energy and food in / waste and profits out out;  And two who have mobilised hundreds of community members to turn around collapsing fish stocks and seabird populations to thriving ecosystems heaving with life.  All of the projects are ground breaking in timing or scale, with relevance internationally for anyone wanting to understand more about creating sustainable futures beyond the confines of consumer choice and citizen advocacy. 
    We would like to mihi Ngāti Tahinga of Tainui, the mana whenua (hapu with territorial rights and authority in the area) kaitiakitanga (gaurdians) of Waingaroa.  Their whare tupuna is Tainui a Whiro. Their marae connects to the Tainui waka, the moana Whaingāroa, the awa Wainui and the maunga Karioi. Leaders from this hapu, notably whaea Eva Rickard,  have led the way in envisioning, advocating, transforming and enabling.  “Don’t wait for permission to do something about it.” Tautoko koutou. (We were unable to interview representative of Ngāti Tahinga of Tainui).  
    In this episode we cover:
    Raglan Naturally
    The community led town plan that was 20 years in the making and recently adopted by the Waikato District Council as the town’s official long term plan. Interview with Gabrielle Parson, Raglan Naturally coordinator and Raglan Community Board member.
    Xtreme Zero Waste
    The community owned resource recovery centre that prevents 75-80% of Raglan’s “rubbish” (read “resources”) from going to landfill.  Interview with Rick Thorpe Xtreme cofounder and Innovations Manager. 
    Raglan Community Energy
    A community enterprise that has Whaingaroa on its way to be Aotearoa’s first energy independent town. Interview with Rick Thorpe, also Coordinator of ‘Raglan Local Energy.’ 
    Whaingaroa Harbour Care
    The riparian planting project has had one of the most successful engagement rates with farmers and fishers in the country.  Interview with Fiona Edwards, Whaingaroa Harbour Care Project manager
    Kari-oi Maunga ki te Moana
    A community led epic trapping project with 350 volunteers regularly checking 2048 traps. Interview with Kristel van Houte,  Kari-oi Maunga ki te Moana  Project Manager.

    New Year's Resolutions for 2021

    New Year's Resolutions for 2021

    We’re bidding farewell to 2020 and a big, hopeful hello to 2021 so time for some intention-setting and New Year’s resolutions.

    Waveney’s found a study scientifically proving we put more stock into the goals we set at the start of a New Year and have more success keeping them vs goals set at other times of the year. We discuss the tips for successful goal-setting, including making them Specific, Measurable, Achievable, Relevant and Time-bound. It’s also important to make resolutions and goals as simple as possible, link them to your personal values, and don’t be unrealistically ambitious with behaviour change. So what can we do for sustainability in the next 12 months?

    Waveney has decided to avoid op-shop clothes shopping to avoid buying a surplus of stuff she won’t wear. Tim has decided, sort of, the opposite! He’s only buying second-hand clothes for the entire year (excluding socks and undies) taking inspiration from the HTSTW Six Items Challenge episode. He’s also buying a second-hand bike to throw his personal weight behind building a more bikable city in Auckland.

    There’s got loads of suggestions for sustainable new year’s resolutions drawing inspiration from previous HTSTW episodes, from the painfully easy, like moving your kiwisaver to a sustainable fund (see Climate Action w/ Erica Finnie from 350.org) to going meat-free on Mondays/doing vegan meals once a week, to the more challenging like knocking out Palm Oil or starting a worm farm or reducing your carbon footprint using FutureFit.nz.

    As always, this is a great opportunity to start eating more locally, more organically and more environmentally minded.

    Eco Pets

    Eco Pets

    In many homes the family dog or cat occupies a special place in our hearts. We cry when they die (and we all secretly think puppies and kittens are cuter than babies). But have you ever stopped to wonder if our modern day pet obsession is “eco-friend or foe”? In this episode Waveney and Tim ask ‘what is the environmental pawprint of our pets?’ and explore what it takes to be a sustainable pet owner. They talk about the best food options; eco-friendly flea treatment; how to deal with toilet waste onsite; and the pitfalls of those incredibly cute dog onesies and all the other crazy consumption we do on their behalf - before finishing with a shout out to the very best of the natural vegetarian pets… guess what pet Tim has always secretly wanted but never had?  
    Plus check out the How to Save the World blog with a special guest writer Alex who shares her ‘cat litter saga’ with us - well worth the read for any pet owners with litter boxes.

    Sustainable Gift Giving

    Sustainable Gift Giving

    This holiday season, we're trying to be conscious of not buying plastic-y, non-Earth friendly gifts for people that they may not even like! So we've got 10 suggestions for sustainable gifts for everyone you will be gift-giving to this year.

    1)     Christmas Crackers from KidsCan
    They’re only $2.50 each from Countdown, Harvey Norman, The Coffee Club and other retailers. Inside you’ll find a party hat, cheesy joke and the chance to win a spa pool, trampolines, toys, and sweet treats instead of a plastic toy everyone throws in the bin.
    Even better, DIY crackers – You can buy the Bang from spotlight, rescue the rest. Creative Junk in Christchurch (who also do gift vouchers) or North Shore Recycling Centre, or wherever is close to you. Whole bag of craft supplies for $10. Hopper in Wellington also have eco-friendly crackers.

    2)     Ethical, natural cosmetics and skincare from Go Native NZ
    Go Native are a premium online seller/supplier of natural, organic and ethical skincare ingredients. Over the almost 20 years the business has been around, they’ve developed a global network of suppliers of essential, carrier and fragrance oils, cosmetic butters, waxes, raw materials, ready-to-go bases, and more. The ingredients must be ethically sourced and where possible they buy direct from the growers, so they can establish a relationship with them. You can buy raw ingredients, made products OR Make Kits which are a really fun gift.

    3)     Nectar Feeder
    A fantastic way to support native birdlife and easy to make yourself (or buy one). Forest and Bird have a great guide on how to make one, the benefits of a nectar feeder and things to remember when you have one.
    To make a sugar feeder, take a one-litre milk bottle and attach the lid to a shallow dish or jar lid. Fill the milk bottle with sugar water and make a few small holes about 0.5cm from the bottom of the bottle. Screw it into the lid and turn the dish upside down. Sugar solution will come out of the bottle and fill the dish to the height of the holes.
    Banks Peninsular Conservation Trust pamphlet (warning: PDF) on care and concerns. Buy ready-made for about $60 delivered to your door.

    4)     A Bee House
    It’s crucial we start looking after our pollinators and a the most effective in the bee family are solitary bees, which need housing while doing their job all day. The ready-made houses start from $30. You can even make these with recycled materials, using a waterproof container (1.5L fizzy drink bottle), wool, air drying clay, string, holy tubes such as bamboo. Video instructions are here and here.

    5)     String Art Kit
    They’re back in fashion and a beautiful way to provide art and stress relief to someone you care about. All you need is a backing board, nails, wool or string and an image. You tack nails in and provide string. Any wooden backing board (renovation off cuts, flatish drift wood, chopping board) will do and any string or wool that isn’t too fluffy will work. Check TradeMe and secondhand craft stores for the best deals. Reverse image tree is here and a feather template is here.

    6)     Sustainable Coastlines Merch
    We love Sustainable Coastlines and you can support their cause AND share their brand. They’ve got jandals made from recovered plastic from the ocean that are 100% recyclable (but very strong and hard wearing - $30), water bottles and t-shirts all available here.

    7)     Inoculated Mushroom Log
    Admittedly, a bit of a weird one but for the right person – a fantastic gift! You can grow your own NZ native Oyster and Shitake mushrooms by using dowel plugs and use own log, see here for instructions. Takes six months to a year for the spores to take, then lasts for years. Note –you can only use a log from a deciduous (hard wood) tree. The log needs a shady spot. Great video (apart fr...

    Plant Milk Review

    Plant Milk Review

    Concerned about the environmental impact of dairy milk? Heard unsettling rumours about some of the plant based alternatives? Confused about your plant milk options? In this episode you can find out how to get hold of delicious, fresh, environmentally friendly milks that are affordable and easy; We go behind the scenes of the world’s massive soybean, almond, rice, oat, coconut, cashew, buckwheat, sunflower and pumpkin seed plantations; We consider the importance of packaging and also the importance of how milk ingredients are farmed (regardless of what crop it is). And, especially for kiwi’s wondering if they should ditch dairy, we dig into how Aotearoa’s farming practices compare to the rest of the world and why “buying local” really matters when you live in an isolated country in a far flung corner of the world’s largest ocean.

    But let’s be honest, if it is too expensive, tastes weird, etc we aren’t likely to ruin our daily caffeine fix for the planet. So Tim and Waveney weave it all together in a one-stop-plant-milk-shop with taste testing, price information and a DIY plant milk demonstration.

    Overall, we pronounce “oat” best in show. It’s one of the only DIY milks that require no soaking (we don’t actually mention on the ep). It is also one of the cheapest options, one of the best for the environment, one of the easiest to buy organically and locally and - rejoice and be glad - it performed very well in the double blind taste tests.

    The recipe used in the episode is:
    1/2 cup of seeds / nuts etc of your choice, soaked overnight
    Discard the soaking water and put the rest into the whiz/blender/bullet.
    Add 2 cups of water in total - just a little at first to ensure everything gets cut up well.
    Use a sieve to strain if you want to. (Most recipes online require you to force it through a cheese cloth, but the faf factor of that was way too high for us).
    That’s it.
    Use any strained out bits in dinner - just throw into whatever your making for a bit more bulk, texture, flavour, nutrition...

    This recipe is the easiest you’ll find online, even easier than popping down the road to buy it. However, for those with the time and desire to create their own award winning plant milks we highly recommend the YumUniverse review of 22 DIY plant milks, (www.yumuniverse.com/plant-powerful-dairy-free-milk) with excellent summaries on taste and nutrition.

    Today Tim talks to Danielle, a Sustainability Advocate and Educator from Live Lightly. Live Lightly is a collaboration between community groups, Auckland Council and other partners that began in 2017 and provides advice for people so they can take personal action to tackle the climate crisis and reduce emissions. Their new initiative is New Zealand’s first gamified carbon footprint tool, called FutureFit and that’s what we’re talking about today.

    FutureFit.nz is a free tool that uses New Zealand emission standards to measure your carbon footprint and give you personalised tips on how you can reduce it. Users fill out a short quiz, get their footprint, then register for free to choose personalised actions. You even get told how YOUR footprint compares to the national and international averages. It covers areas like Energy use, Transport and Food choices, and gives ready-to-apply tips on how to make positive changes. Some are one-off actions, some are ongoing behaviours.

    Tim gets assessed and gets some worrying news about his carbon impact and gets recommended choosing local produce to bring it down. Danielle breaks down what a carbon footprint actually is and we have a discussion on individual and systemic change.

    Check out FutureFit.nz right now and register as an individual, a household, a workplace or a group of friends.

Love this NZ based podcast!
Love that it’s about sustainability, based in NZ and such a positive tone! I’m always learning something and getting inspired!
Wave and Tim are great- funny, informative and chatty.
Most memorable episodes are the soil episode, the fair trade episode, the one with dai henwood, the bee episode and the recent gift giving episode. I actually think there’s too many to list!
