The IRD has occupied the ground floor of the premises for the past 15 years. Its naming-rights' tenancy generates a rental of $186,684 per annum and runs through to later this year, with two further three-year rights of renewal.
McCallum says the IRD has sub-leased some of its space to other Government agencies including Internal Affairs and the Ministry of Innovation and Development.
"The IRD and its sister government agencies on the ground floor have maintained the standard of their interior throughout their tenancy. This reflects not only the professionalism of their services, but also meets the Government edict that all state offices must be housed in earthquake-resilient premises.
"Extensive renovations of its floor space currently being undertaken by the IRD include the installation of a new access and security system, new interior decor and fit-out, and an upgrade of the closed circuit TV camera electronics and office security layout."
The building is located on the northern fringe of Invercargill CBD in the city's large retail precinct adjacent to well-known stores like Farmers, Rebel Sports and Briscoes, and in part of town zoned Business Sub Area which allows for a mix of retail and commercial activities.
McCullum says the building has 20 onsite car parks and, with around 100 employees working inside the building, both tenancies have their own individual staff amenities - including bathroom and kitchen facilities.
"The property exceeds 100 per cent of New Building Standard [NBS] under the Initial Evaluation Process [IEP] assessment method and buildings with ratings higher than 66 per cent are generally considered 'safe'.
"The property has a 2014 rating valuation of $3.6 million and we have already received interest from potential buyers in Canterbury, Tauranga, Auckland and Southland."
McCullum says that, from an investment perspective "on multiple fronts", there are few buildings like 45 Yarrow Street in Invercargill which house quality national and leading provincial tenants in modern and well maintained premises.
