Okay - That's the same as you put in your OP, but it doesn't make any sense.
I suspect you mean 3kw (which is at the low end I think), but I suggest you read around the subject a little to better understand, or maybe best to just get installers to come in and do it all for you (including suggested specs) as part of quoting.
Good luck!

You will have calculated what size heatpump will be suitable for you
I installed midea heatpump in our house we brought. It cost me about 640 NZD each for a 2 kw max heat out unit
And a 7kw max heat out unit for 1k NZD .They are decent for price
If you want the best them Daikin is what you should consider. Next best option will be ME AND mhi
General rule of thumb you can go size smaller but can't go size up as ihp can not regulate temperature Better
Cheers how much did the installation cost you? I've been quoted 1500 + gst for a midea install
700 cash with separate power line for fuse box though not needed i would suggest separate circuit for midea ones as it has a function ( it does automatically ) to heat the outside unit when its cold and it will pull lot more power . also including wall mount brackets
Cash work on electrical circuit means no Insurance coverage. If anything goes wrong, you are on your own. I won't risk my house for small saving which has a potential of exponentially blowing back financially if something goes wrong.
@ace310: Na mate the guy who did it is a Electrician and works for a major company he was trained by Fujitsu and doing HVAC since many years and if I need can also provide certificate of compliance, we had done electrical work on entire house and we went for old ceramic switches to rcbos our house didn't even had ground when he brought it . And there fire spark marks on all bulbs fixtures when they were removed this was on the entire house .
@desikiwi: That's good. I am not questioning the electrician or the work he did. But to get certificate, he would need to properly invoice the work which means paying GST. Atleast that's my understanding, could be wrong. It's good that he can provide the documents, but back dated documents can be tricky when the need arises.

I believe it also has to be properly inspected and signed off by another electrician (inspector).
The trouble is, you would probably only 'need' that certificate if a problem had already arisen (trying to do an insurance claim for example), and if there was a problem, nobody is going to retrospectively sign it off.
I could be wrong, and haven't read all the regulations in detail, but I'd imagine the EWRB site would have a lot of info.
I paid $600 for back to back install of Midea, from Trade Depot installer in Auckland - Brian, Airflow EMS, 0210 898 8524
When you say, '3kwh' what do you mean exactly? 3kwh is a measure of an aggregate amount of energy, rather than the 'power' of an air conditioner, which would be measured in kw, and when run for a period of time, would consume an amount of energy:
kw multiplied by time (hours) = kwh
A 1kw unit run for 3 hours would consume 3kwh of energy
A 2kw unit run for 90 mins would consume 3kwh of energy
A 100W light bulb run for 30 hours would consume 3,000 watt hours (3kwh) of energy
Any appliance running at more than 2.4kw (2,400 watts) should not be run from a standard ring-main in NZ, as they are generally limited to 10 Amps, else a fuse could blow. Power is Voltage multiple by Current, and mains voltage in NZ is around 230V (230V +/- 6% I think, but I'd have to check to be sure, which would mean a low of about 216V and up to about 244V).
An appliance receiving 240V and drawing 10A would run at 2,400 watts (2.4kw), which should be about the limit of anything sold in NZ to 'plug in'.
If you meant 3kw (rather than 3kwh) then it would require installation by an appropriately qualified electrician in which case, I would suggest contacting various installers around you and asking for quotes.
Personally, I would be cautious about purchasing a unit that required installation, and then contracting someone to do the installation, as it could leave a 'gap' for the vendor and installer to blame the equipment / installation if something was not working properly. If you get someone to supply and install, it is fairly unambiguous that they are responsible to you.
HTH,
