In 2011, the 100 per cent NZ Bacon & Ham Competition received 238 entries from 70 businesses.

Magills Meats' streaky bacon was named one of the top rashers in New Zealand in 2011 - owner Mike van der Hoeven being awarded a silver.
Mr van der Hoeven developed the bacon with European small goods manager Mihai Oltean.
"We worked on the silver award winning dry cured bacon for almost three months and I'm more than satisfied with the results," Mr van der Hoeven said at the end of last year's event.
But he was also determined to 'go for gold' this year.
Mr van der Hoeven says the streaky bacon is back - but they have perfected the product and it's even better than last year.
Magills have also entered their standard bacon and dry cured ham and are looking forward to good results.
Entries close on Friday, June 22.
The 100 per cent NZ Bacon of the Year and Gold, Silver and Bronze bacon medallists will be announced on July 23 and the 100 per cent NZ Ham of the Year will be announced in late October.
