"It's anything involving twisting," she said.
For example, injuries occurred when people twisted around to pull open a curtain while still half in bed.
According to ACC, the injury claims included "tripping over the bed", "hurting back while making the bed", and "falling off the bed".
Top bed-related injuries were sprains, strains, fractures and dislocations. However, high numbers of lacerations, punctures and even stings in the bedroom were recorded.
Previous ACC data showed New Zealanders were particularly mopey in the mornings, with nearly 150 people each week injuring themselves getting out of bed in 2011.
Mrs Anderson said some unlucky Wairarapa residents had also hurt themselves making their beds.
"You're bending down to tuck the bottom of the sheet or something, so it's usually a lower-back injury. There's a little bit of twisting and, of course, you're bent over - so that's pretty common."
Nationally, more than $5 million was paid out for bed-related injuries between 2010 and 2013 - representing more than 6500 claims.
While specific causes of bed-related injuries were not recorded in claims data, ACC spokeswoman Stephanie Melville estimated most related to falls in the bedroom.
Slips, trips and falls accounted for nearly half of all home injuries, ACC data showed.
"Around 280,000 Kiwis were injured in home falls last year," Ms Melville said.
"Ten-thousand people were off work for more than a week [and] 2500 were off work for three months or more."
Injuries in the bedroom and around the home could cause major problems, she warned.
"They can disrupt family plans, cause tensions in relationships and put pressure on households having to survive on a reduced income.
"It's also worth remembering that falls not only cause physical pain but can have a wider cost to families, employers and the economy."
