How it works

Who can participate?

All public and private pre-, primary, intermediate, special and secondary schools in New Zealand are invited to join the Colgate Community Garden Challenge.


How do I join the competition?

During the competition period, schools will earn Garden Points by sending oral care waste to TerraCycle for recycling, and by earning online votes from the community.

1 unit of oral care waste = 10 Garden Points

1 online vote = 1 Garden Point


Earn Garden Points by Recycling

Follow these four easy steps to participate:

1. Join the Colgate Community Garden Challenge. Click 'JOIN THE PROGRAMME FOR FREE' at the top of this page. If your school was signed up to the 2018 Colgate Community Garden Challenge, you're automatically in the running to win. 

Important: Your school must be registered in the Colgate Community Garden Challenge in order to participate. Make sure you've listed your Organisation Type as either 'Pre-school' or 'Primary School' or 'High-School' in your TerraCycle account.  

2. Start collecting oral care waste. Collect used oral care products in any old box or bag. Once your box is full, log into your TerraCycle account and download the free shipping label via the Colgate Community Garden Challenge page.

3. Send us your waste for recycling. Stick the shipping label to your box or bag of oral care waste, and drop it at the closest New Zealand Post office. Sending your oral care waste is free-of-charge!

4. Earn Garden Points. Every piece of oral care waste received by TerraCycle between 19 August 2019 and 15 November 2019 will count towards your total Garden Points. Each unit of used, post-consumer oral care waste will count as ten (10) Garden Points. The more waste you send, the more chances you have to win!

Important: Schools with multiple TerraCycle accounts must use the same account each time you send in a shipment of oral care waste. This way, all of your entries will appear in a single account. 

Earn votes from the community

Schools can earn additional Garden Points through online votes from the community. Voting will be open from 22 August 2019 to 15 November 2019. Each vote will count as one (1) Garden Point. To earn more online votes, spread the word about your participation using posters, social media and word-of-mouth!

Grand Prizes

There are two (2) community garden sets up for grabs, each worth over $3,000! (Total prize value: 9,316$). Each community garden set includes:

  • One (1) recycled garden bed
  • One (1) custom-made bench
  • One (1) $300 MITRE 10 gift voucher to buy gardening supplies

The school which accrues the most Garden Points in total (based on the weight of the total amount of shipments & total number of votes) will win a recycled community garden set.

Schools will receive one entry in the final prize draw for sending in at least 1 eligible shipment during the promotion period for the chance to win one recycled community garden set. 

Participants are only eligible to win one (1) community garden set. 

Monthly prizes

For every month from August to November, all schools that send a shipment of oral care waste to TerraCycle will receive 1 entry in the monthly prize draw for that month for the chance to win a prize pack of 100 upcycled lunch bags, valued at $1,028 per pack! (Total prize value: $3,084).

Limit of one entry in the monthly prize draw per participant per month. Participants are eligible to win one (1) pack. 

Additionally, for any shipments of approved oral care waste over 5kg received by TerraCycle, schools will earn $0.02 per piece of waste to allocate to themselves or a nominated non-profit organisation.

Each shipment can weigh a maximum of 25kg. Total prize pool $9316.88.

What you can recycle in this programme

Programme accepted waste: Any brand of used toothpaste tubes, toothbrushes, plastic toothbrush packaging, interdental brushes, wisps, pumps, stand up toothpaste bottles, mouthwash bottles and any kind of non-electric toothbrush or toothpaste tube and all affiliated non-recyclable packaging.

Best practices for recycling

In order to recycle this waste stream properly, please make sure all excess product has been removed (i.e. leftover toothpaste or floss). Additionally, if you choose to rinse your product, please note that it must be completely dry prior to shipping. You cannot ship dripping packages.
