As well as the signed guitar she had managed to snag two tickets to Bruce Springsteen's upcoming concert along with a signed framed record and photos of the singer.
Among the sporting memorabilia up for grabs is a signed All Blacks jersey.
The event will benefit Rotorua police Detective Steve Allpress, who is undergoing treatment for terminal brain cancer.
Fund committee member Sergeant Phil Wilkinson said they had talked about setting up the fund before Mr Allpress became sick but it was kicked into gear after an incident at Onepu in March when four police officers, three from Rotorua, were shot and injured in the line of duty.
Mr Wilkinson said the fund would be used to help sworn and non-sworn staff and their family members who suffered trauma, illness or injury.
All Black great Michael Jones is the guest speaker and Police Ten 7's Rob Lemoto is the MC.
There will be live music from Bayley Howard followed by Kelly Makiha.
Mr Wilkinson said 80 per cent of the money raised would go towards Mr Allpress' family with the remaining money going to the fund.
Tickets can be bought from www.nduro.co.nz or by using the "book now" link on the Rotorua Police Welfare Fund Facebook page.
Anyone wanting to donate items for the auction or money to the cause can send a private message to the Facebook page.
