Ashburton District Council is trialling new rubbish bags over the next couple of months to make sure they can stand up to the district's waste.
Council is changing its supplier of the official black rubbish bags which get picked up during kerbside collection and is currently testing the proposed new supplier's product to ensure it is good value for money.
Waste Recovery Manager Craig Goodwin says the trial is an important part of the selection process as Council wants to be certain the new rubbish bags are fit for purpose.
"These trial bags are much more durable and stronger, but we don't really know how they will perform until we test them out.
"Anything we can do that is cost effective and provides a better service, we're willing to give a go."
The kerbside collection team will be able to identify the trial bags which will be blue, are made from a different material and have an official Ashburton District Council sticker on them.
The new rubbish bags are available at Council reception at the same price as the standard black bags.
If the trial is successful, the new bags will be phased in from late June at which point they will be black and look exactly like the old ones – the blue colour is just for the purpose of the trial.
Council is also going to trial the sale of single bags with New World customers able to purchase bags individually rather than in a pack of five.
Mr Goodwin says the single sale offers residents more choice by being able to select the amount which best suits their requirements as not everybody needs to buy five bags at a time.
