England rugby shirts are to be hidden in Norwich on Saturday in build-up to the World Cup

A clothing company is planning to hide three T-shirts in Norwich to set what it described as 'the ultimate test' of England rugby fans' commitment to the team.

The marketing ploy will see the city chosen as one of six locations where Canterbury will put a wooden crate containing three England world cup T-shirts.

Fans will have to follow the Twitter account of the company, @CanterburyNZ, in order to work out where the crate has been hidden tomorrow morning.

The company, which was founded in New Zealand in 1904 and whose logo includes the New Zealand rugby team's kiwi symbol, said fans would then have to 'complete a specially designed challenge that will test the perseverance and skill of the most devoted England supporters'.

Once they think they know where the wood box is, those who get to it first will become 'one of the very first to get their hands on the new England shirt for the Rugby World Cup'.

Those who arrive later will receive a discount voucher to buy items from the company's website.

Canterbury Global VP of product and marketing, Ian Nelson, said; 'Fans are at the heart of our campaign and we wanted to reward their commitment to the rose by giving them the chance to get their hands on their very own England shirt in a fun and innovative way. We want to ensure that the whole nation celebrates what is sure to be an incredible World Cup on home soil.'

The company has previously provided playing shirts to the New Zealand and Australia teams, and is now team kit supplier to England Rugby and Ireland Rugby as well as Bath, Leinster and Cardiff Blues.
