The trial of a Napier man accused of sexually abusing and torturing his partner for more than 2.5 years is in its closing stages.

Timothy Hebberley is on trial at the High Court in Napier, on 28 charges including injuring with intent, sexual violation, kidnap, intimidation, rape and threatening to kill.

The Crown withdrew one charge of sexual violation on Friday.

It's alleged the 20 year old branded his partner with hot wire, burnt her with lighters and candle wax, intentionally dislocated her limbs, and locked her in a small room with a dangerous dog for two hours.

The Crown and Defence will sum up each case today, and the jury will retire to consider its 28 verdicts from tomorrow.
