Why then is it so popular and appears to work satisfactorily in countries like New Zealand?

Considering this is the RHI document in full
http://www.decc.gov.uk/assets/decc/...newableheat/1387-renewable-heat-incentive.pdf
and it specifically states
Air source heat pumps
Air source heat pumps will not be supported from the outset, as more work is needed to better understand the costs associated with the technology and, for air to air heat pumps, as described below (Direct air heating), we have not yet developed a means of measuring direct air heating, as we have for water and steam. Subject to the successful conclusion of the work and affordability, we will look to extend eligibility for air to water source heat pumps from 2012.
I would guess you may need to rethink.
This is the latest spiel from DECC. The last sentence is the interesting one.
Treatment of air source heat pumps under the RHI
Air source heat pumps can heat air directly (air to air heat pumps) or use water as the heating medium (air to water heat pumps).
In the medium to long term, we anticipate both of these technologies being deployed widely in the UK across all sectors and playing a significant role in meeting our renewables and carbon targets. We recognise an incentive may be required for that to happen.
The work undertaken by our consultants showed that currently the majority of heat pumps in the commercial and industrial sectors were air to air. In the domestic sector, air to water heat pumps are the predominant technology.
We do not have evidence for the costs of air to water heat pumps outside the domestic sector and are not in a position to provide support for that technology from the start of the RHI.
For air to air heat pumps we need to resolve several issues before we will be ready to include them in the RHI. This includes resolution of how to measure direct air heating, including separating out the heating and cooling output. There is also the wider question of how best to provide support for a technology which is often installed for the purpose of providing cooling to a building but which we also want to be used for heating.
We will be considering how we can include all air source heat pumps in the RHI from 2012.
In the meantime, air source heat pumps in the domestic sector will be eligible for the Renewable Heat Premium Payment, further details of which will be announced in May.

And from 2016 all new builds will have to come with energy supplied from a renewable source.
So even if you wanted a gas boiler etc fitted in your new home, it will by then have become illegal to do so!!
Servotech,

No, all new houses have to be carbon-neutral by 2016, which is not quite the same thing.
Because they have a warmer average climate...
And there was me thinking it was the gas industry pushing it wares on the back of north sea gas, which seems to be running out now, but never mind that nice man Mr Putin has lots which he'll let us have for next to nothing.

Code 6 wil see very few gas fired products installed,the only exception may be Gas CHP.

i really don't see what you're hoping to gain here?
Sure we all know we are -supposedly- running out of natural resources but electricity is going to become more and more expensive as gas fired generator plants currently account for roughly 40% of supply..Renewables are a dead duck, Nuclear power stations need 20 years start to finish
I can buy these things at trade and install at cost and I am sticking with my nice reliable Worcester Combi for many years to come.. I am happy with my decision as I'm sure you will be with yours..
