Chase Property Management director Sam Coutts pointed out the city looked to become, to some degree, unaffordable if wages did not mirror the growth in rent prices.
The report said the average rental price for a three-bedroom home was now between $450 to $550 per week.
When taking into account four weeks' bond and another week's worth of rent to a letting agency, potential renters needed to have at least $2500 to secure a home.
Mr Coutts said landlords had the power to raise rent prices every 180 days, while a letting agency could raise rent $10 a week each year.
The report offers renters a few tips:
• Get your references together and aim for them to be impeccable.
• Be one of the first people to apply. With an average of 80 people applying for each property, getting in first always helps.
• First-time renters or students should speak to their parents about acting as guarantors.
"The main thing landlords look for is that the rent is being paid and the property is being cared for and clean."
