Institute of Environmental Science and Research (ESR) scientist Janina Savage gave the jury her analysis of multiple blood and footprint samples taken from Mr Waipouri's flat.
The jury also viewed several blood-soiled clothing items, taken from the accused men, and a portion of bloodied couch covering. Candles with hair embedded in the wax, a knife, and scissors, all covered in blood, were presented by Ms Savage. The case so far:
* The two unemployed men charged with Mr Waipouri's murder on December 23 last year are Ashley Benjamin Arnopp, 20, and Andre Gilling, 18. Both pleaded not guilty to the charge.
* Mr Waipouri died from a "multiple application of blunt force trauma" in a sustained attack lasting about an hour.
* Both men accused were arrested at the scene and are said to have been socialising with Mr Waipouri at his Rangitikei Street flat the day and night before.
* Those accused are said to have consumed alcohol, as well as party pills and cannabis.
* The trial is presided over by Justice Allan Mackenzie.
Ms Savage was to give further evidence today and undergo cross examination from defence counsels, Mike Antunovic (Gilling) and Greg King (Arnopp).
